I received an email from a reader the other day who was involved in a bad accident while towing a trailer 5 years ago. The accident was a result of a sudden wind shear, causing the trailer to start swaying out of control. The truck and trailer rolled over. Fortunately everybody was okay!
After detailing the accident, Mary who was driving at the time, asked me if I had any hints or tips to offer on trailer brakes, controlling sway, and what to do when you experience something like wind shear, cross winds, or towing in windy conditions. After reading Mary’s email I thought it would be an appropriate topic for an article.
Let me begin by saying that the safest measure for traveling by RV in windy conditions is not to travel at all. RV’s have a great deal of mass (length, width & height) and when that mass is confronted with strong wind gusts, crosswinds and/or wind shear the results can be devastating.
Sometimes the weather forecast can warn us that windy conditions are expected. These are the days that you need to make a conscious decision to stay put at the campground, or wherever you might be, and not take a chance traveling by RV. Trust me when I say it’s not worth the risk involved.
On the other hand what do you do when you are traveling on a fairly calm day and suddenly you are hit by a strong wind gust or crosswind? If you’ve been traveling by RV for awhile, either motorized or towable, you have probably experienced the forces of wind against the RV at one time or another. Possibly the most common occurrence is when a transfer truck passes you from the rear. I refer to this as the push, pull effect. The force of the air pressure coming off of the truck as it begins to pass pushes against the side of the RV and as it completes the pass it pulls you back in again. If you are not aware of the truck passing you, or if you are towing a trailer and don’t have some type of sway control this air pressure can cause the trailer to start swaying. The same dynamic occurs when a sudden wind gust hits the side of the RV unexpectedly.
The forces of air pressure are not the only thing that will cause a trailer to sway. Sway becomes an automatic factor with travel trailers simply because of how the trailer is hitched to the tow vehicle. The good news is that even though the potential for trailer sway is there, it can be controlled. Let’s look at some of the causes for trailer sway.
First and foremost poor trailer design contributes to trailer sway. When there is too much weight behind the trailers axles causing the tongue weight to be less than 10% of the trailers weight it has a natural tendency to sway.
*Incorrect tire inflation.
*Improper weight distribution hitch adjustments.
*No sway control on the trailer.
*Crosswinds
*A transfer truck passing from the rear of the trailer.
*Descending inclines
*Towing speeds and hitch weight
*Tow vehicle not properly matched for the trailer.
*Improper loading, overloading and poor weight distribution.
So, what can you do about it when it happens to you?
Most of these causes for trailer sway have quick and easy fixes. For starters, before you purchase a travel trailer, do your homework on the trailer. A poorly designed trailer will never handle well. Find a trailer with a tongue weight that is 10 to 15 percent of the trailers weight and match it with a tow vehicle that is capable of handling the load.
It is safe to say that with a well designed trailer, the proper tow vehicle, correct tire pressure, correct hitch adjustments, sway control and a properly loaded trailer we can control a great deal of potential trailer sway. That narrows the potential for sway down to what you could encounter at any given moment, even with a stable trailer; strong crosswinds, transfer trucks passing from the rear, bad driving conditions and descending steep inclines. Any one of these conditions will tend to push the trailer and tow vehicle sideways, but when equipped with the proper type of sway control and brakes, you can make normal steering corrections.
If the trailer become unstable and attempted steering corrections don’t control it you can use the manual override on the electronic brake control to regain control of the trailer. Slide the manual lever over slowly and allow the trailer brakes to engage and the sway control to put the trailer back on a straight course. If trailer sway becomes severe, reduce your speed gradually, avoid using the vehicle brakes if possible and manually apply more trailer brakes.
The brakes on the tow vehicle and trailer are a critical element to safe towing. Electric brake controllers are an essential component to safe trailer towing. The brake controller is installed inside the tow vehicle and supplies the power from the tow vehicle to the trailer’s electric brakes. There are two types of electric brake controllers, time delay activated and inertia activated. Time delay or solid-state controllers apply gradual voltage to the trailer brakes using a time delay circuit. A pendulum circuit that applies gradual voltage to the trailer’s brakes activates inertia or pendulum type controllers.
Both types of brake controllers allow you to adjust the amount of braking power and they both have manual overrides that can be used to activate the trailer brakes without using the vehicle brakes. The override feature can be used when descending an incline, to assist in slowing down and to prevent premature brake wear on the tow vehicle. It is also helpful in regaining control if the trailer begins to sway or fishtail. Always check the operation of the brake controller and trailer brakes before leaving on a trip.
*Have your trailer brakes, bearings and other components inspected at least once annually by a professional.
*Allow more distance for stopping then you are accustomed to. Do not follow other vehicles too closely.
*Do not use the tow vehicles brakes to control excessive trailer sway. This will usually make it worse. Manually apply the trailer brakes to regain control.
*When descending a steep incline, if it feels like the trailer is pushing the tow vehicle, reduce speed, down shift to a lower gear and use the manual override on the brake control to slow the trailer. Heavy use of the tow vehicle brakes can cause them to overheat and begin to fade.
*Always be prepared to slow down and try to avoid making sudden stops.
Passing Vehicles
*Allow more time for acceleration when planning to pass somebody. It may be necessary to shift out of overdrive for increased acceleration.
*Only attempt to pass a vehicle on a level road surface. Never attempt passing on steep upgrades or downgrades.
*When passing a vehicle or changing lanes, signal in advance and double check mirrors for oncoming traffic.
*When completing a pass, look in your mirror, if you can see both of the vehicles front tires on the road surface behind the trailer it is safe to signal and pull back in that lane.
*When passing, or being passed, anticipate the need to make steering corrections due to the air pressure created by other vehicles.
*Always be cautious of the road shoulder when passing. If the trailer gets on the shoulder it can jackknife or cause you to lose control.
Upgrades and Downgrades
Some vehicles have transmission tow modes. Consult your owner’s manual for the proper gears to use on your tow vehicle when towing a trailer.
*Downshift on downgrades to lessen the braking action required. Reduce your speed. Remember that trailer sway is more likely to occur when descending inclines.
*Downshift on upgrades for increased acceleration and power.
*On steep or long downgrades, reduce gears and avoid prolonged brake use on the tow vehicle. The brakes can easily overheat. Use the vehicle brakes in intervals.
*If the trailer becomes unstable when descending an incline and the trailer starts to sway, reduce your speed, avoid using the vehicle brakes, and manually activate the trailer brakes to regain control.
*On steep or long upgrades monitor all of the gauges on the tow vehicle instrument panel. If gauges do not read in the normal range, or the vehicle starts to overheat, pull over as soon as you safely can and call for help.
Safe Driving Tips
Some of these tips apply to pulling a trailer, some apply to driving a motorhome and some apply to both.
*Don’t speed. Driving at a moderate speed will put less stress and strain on the drive train components of your tow vehicle. It will also reduce the likelihood of the trailer becoming unstable and starting to sway.
*Monitor the gauges on the tow vehicle or motorhome instrument panel. If a gauge does not read in the normal range pull over as soon as it is safe, and call for help.
*Drive defensively! Stay alert and monitor what is going on around you at all times. Use your mirrors. For increased visibility, purchase some convex mirrors that you can apply on your side view mirrors. These mirrors are inexpensive and are available in auto parts stores. They come in different sizes and will improve your visibility a great deal, especially along the sides of the RV and in blind spots.
*If you’re pulling a trailer it may be necessary to add mirror extensions so you can see along the sides of the trailer. The mirrors on your tow vehicle can be your best friend when you’re towing a trailer. When you use your mirrors you will know when a transfer truck is passing, and you can anticipate the need for a slight steering correction when the trucks air pressure causes the trailer to move.
*Use the proper gear for driving conditions. If the transmission continues to shift in and out of overdrive you need to turn the overdrive off. Reducing gears can help to slow the trailer or motorhome down when descending inclines and give you the additional power you may need when ascending inclines.
Note: Read the tow vehicle owner’s manual for proper gear selection when towing.
*Try to avoid sudden stops. Stopping to quickly can cause a trailer to slide and possibly jackknife.
*Try to avoid quick, harsh steering movements if possible. This can cause a trailer to become unstable and increase the possibility of trailer sway.
*Slow down on loose road surfaces, such as gravel, and when the roads are slippery and wet.
*When towing a trailer or a vehicle behind a motorhome you need to make wider turns than you are accustomed to. Remember the pivot point for the trailer is its axles. Watch for tail swing and exercise caution when turning on narrow streets and maneuvering around fuel stations.
*When maneuvering around the campground, watch for tail swing, low branches and utility hook ups.
Happy Camping,

RV Business Indicators from RVIA
March 3, 2009
Prepared by Recreation Vehicle Industry Association
Several positive factors point to recovery when credit availability and job security:
Primary demand for RVs remains robust, as indicated by solid RV rentals and strong RV show attendance this winter. Low consumer confidence and America’s struggling economy are causing consumers to delay major purchase decisions. A delay in purchasing means future sales potential and renewed growth in future shipments.
RV show attendance and sales have encouraged RV dealers and manufacturers. Dealers exhibiting at shows in Florida, Washington, Oregon, Colorado, Kansas, North Carolina, Massachusetts, Michigan, New Jersey, Pennsylvania, Nebraska and Maine reported surprising attendance and sales, which they attributed to pent-up demand and the desire of consumers to burst out of the malaise affecting the economy. Sales exceeded expectations and consumers generally displayed a positive attitude.
The credit worthiness of RV consumers remains at the top of all credit seekers. The delinquency rate on RV loans was 0.95% from 1999-2007 vs. 2.0% for other consumer loans, according to the American Bankers Association Quarterly Delinquency Bulletin. Current limitations on RV credit are expected to gradually diminish over time since RV owners are, on average, excellent credit risks.
Federal economic credit and stimulus packages, which include provisions to stimulate RV lending and friendly tax treatment for new RV purchases, may help promote sales and aid in the RV industry’s economic recovery. One provision in the stimulus bill provides a deduction for sales or excise taxes on the first $49,500 of a new motorhome purchase. Inclusion of RV consumer loans and RV dealer floor plan loans in the Term Asset-Backed Securities Loan Facility (TALF) could ease credit and stimulate RV lending.
RV Shipments and Sales Data
2008 shipments. 2008 RV shipments were down 32.9% from 2007. The industry shipped a total of 237,000 units. Dr. Richard Curtin, Director of Consumer Surveys at the University of Michigan, said that total RV shipments declined in 2008 due to the tightest credit conditions in several decades, higher interest rates, falling household wealth, slower growth in real incomes, and the crisis in consumer confidence.
2009 projection. As the current recession is expected to affect all sectors of the economy, RV shipments are expected to be lower in 2009 as well. Credit restrictions are causing RV buyers to delay purchases and RV dealers to keep inventories low. Sales in 2009 will be affected by stringent credit standards, falling employment, and continued declines in household wealth and home prices. Dr. Curtin predicts 2009 shipments will total 130,100.

Shipments history. After five consecutive years of record growth, RV shipments dropped 9.5 percent in 2007 as consumers postponed discretionary purchases due to the U.S. economic slowdown. Shipments totaled 353,400 — the fourth highest in the past quarter century. 390,500 RVs were shipped in 2006, the best annual total in the past 25 years. Total RV shipments in 2006 were 1.6 percent higher than 2005 — the fifth consecutive year shipments grew. RV wholesale shipments totaled 384,400 units in 2005. In 2004 RV shipments topped 370,100. For a historical chart showing RV shipments by year, go to: RVIA Historical Glance.
RV Travel Trends
RV ownership and travel is a great value. The 2008 PKF Vacation Cost comparison study showed that a family of four can save 27-to-61% on vacation costs by traveling in an RV, after factoring in ownership costs and fuel. Even with higher fuel prices, more than 80% of RV owners say their RV vacations cost less than other forms of vacation.
Shorter trips close to home. Research shows that RVers spend more time enjoying campgrounds and less on the road to save fuel. With more than 16,000 campgrounds nationwide, RVers also save by staying closer to home.
Fuel cost analysis. Analysis of potential fuel cost increases shows that fuel prices would need to more than triple over current levels to make RVing more expensive for a family of four than other forms of travel. Airfares and hotel rates are rising rapidly as fuel costs increase. “While fuel costs are a component of the overall vacation cost, fluctuations in fuel prices aren't significant enough to affect a family's decision of whether or not to take RV trips over other types of vacations," said Kannan Sankaran, PKF's lead researcher for the study.
Campgrounds and RV rentals held their own in 2008, despite difficult economic conditions. Campground business remained steady in 2008, down slightly from a record year in 2007. According to the nation’s largest RV rental companies, RV rentals were flat to slightly up in 2008.
Other Factors Behind RV Industry Growth
IRS tax deduction. For most RV buyers, interest on their loan is deductible as second home mortgage interest.
Lifestyle trends continue to spur demand for RVs. RV owners overwhelmingly said in recent surveys that their RV makes it easier to take more frequent weekend getaways or mini-vacations that accommodate busy family schedules. Nine-of-ten RV owners take three or more short trips (1-4 days) in the spring and summer, according to surveys. Research by the Mayo Clinic concluded that Americans need to take mini-vacations from the usual routine to reduce the anxiety, irritability, insomnia and depression that results from excess stress.
Go RVing ads build demand. More than two million consumers have visited GoRVing.com in 2008 as the industry continued its aggressive outreach. The ads have been updated with a new theme line for 2009, “Go Affordably. Go RVing.” Details: GoRVing.com.
Indicators for Future Growth
Population and demographic trends favor long-term RV market growth. Buyers aged 35-54 are the largest segment of RV owners, according to the 2005 University of Michigan study commissioned by RVIA. The demographic tidal wave of prime RV buyers remains strongly in the strongest RV ownership age groups. Every day, 11,000 Americans turn 50, according to U.S. Census figures.
Boomers nearing retirement. RV sales will benefit as aging baby-boomers continue to enter the age range in which RV ownership is highest. According to Dr. Richard Curtin, director of surveys at the University of Michigan, by the end of the decade, the number of consumers aged 50 to 64 will total 57 million — 38 percent higher than in 2000. Today one-in-10 vehicle-owning households in that age group own at least one RV.
RVs are also attractive to young buyers. The fastest growing group of RV owners is young people 18-34. Products such as sports-utility RVs, as well as the Go RVing campaign, have helped attract younger buyers.
RV manufacturers are innovating to give consumers an array of product choices. Manufacturers are producing lightweight towables and smaller, fuel-efficient motorhomes. Green technologies such as solar panels and energy-efficient components are appearing on an increasing number of RVs.
RV ownership has reached record levels. Approximately 8.2 million American households now own an RV — a 16 percent increase since 2001 and a 64 percent gain since 1980.
Vast potential market. By 2010, RVs will be owned by 8.5 million households, outpacing overall U.S. household growth of six percent, the Michigan study forecasts.
Purchase intentions are higher now compared to what the Michigan study found in 2001 and 1997. Two-thirds of current owners plan to purchase another RV. Among all U.S. households, nearly one quarter (23 percent) intend to purchase an RV in the future. Details

RV Terminology D through G
I guess because I work in the RV Industry and around RVs almost everyday I take some things for granted. One of those things is RV terminology. When you hear these terms everyday you just assume that everybody understands them. For the new RVer terminology may be a bit confusing. To help clear things up, I’d like to offer some common RV terms that you will encounter during your RVing experiences.
D
Deep Cycle Battery - Often referred to as the auxiliary battery(s) or house battery, it is used to supply 12-volt DC power to the appliances and accessories in the RV. Unlike an automotive starting battery they are designed to hold a charge longer and be discharged repeatedly. The RV battery(s) is charged when the motor home is running, or in the case of a trailer, when the tow vehicle is running, if a charge line was wired in to the trailer plug. It is also charged when the RV is plugged in to a 120-volt power source and by an onboard generator.
Delamination - When the filon, (fiberglass panel) separates from the luan backing used to construct fiberglass sidewalls on an RV. This is usually caused by water damage.
Demand Water Pump - The onboard water system that operates off of a 12-volt demand pump. When you have potable water in your fresh water holding tank and the pump is turned on it pressurizes the onboard water system. When you open a faucet and the water pressure drops the pump cycles on and off to maintain a constant pressure.
Diesel Pusher - A motor home with a rear mounted diesel engine. Often times referred to as a pusher.
Dinghy - A term used for the vehicle you are towing behind the motor home.
Dry Camping - Camping in an RV without any utility hook-ups (water, electric, sewer). You can still use all 12-volt appliances and accessories as long as the deep cycle battery(s) has a charge. You can also use the onboard water system with the 12-volt demand pump and if you have a generator you can use the 120-volt appliances and recharge the auxiliary battery(s). This is what makes an RV fully self-contained.
Dry Weight - Dry Weight (DW) or Unloaded Vehicle Weight (UVW) is the actual weight of the RV as built at the factory. The DW does not include passengers, cargo, fresh water, LP gas, fuel or after market accessories.
DSI- Direct Spark Ignition (DSI) - is a system used to ignite the burner on a propane appliance with the touch of a button. It is commonly used on RV refrigerators, furnaces and on some water heaters.
Ducted A/C and Heat - When the A/C and heat is supplied throughout the RV using a ducting system. A/C is ducted in the ceiling and the heat is ducted in the floor.
Dually - A pickup truck with two tires on each side of the rear axle.
Dump outlet - Where both holding tanks terminate into one main outlet. This is where you connect the RV sewer hose to dump or empty the gray and black water holding tanks.
Dump Station - An area designated and approved for dumping or emptying your gray and black water holding tanks.
E
Electric brakes - Trailer brakes are electric and are activated when the tow vehicle brakes are applied by means of a brake controller installed in the tow vehicle.
Empty Nester - When all of the children are finally out of the house.
Equalizing Hitch - An equalizing hitch, or weight distributing hitch uses additional hardware (spring bars and brackets) to distribute a percentage of the trailer’s tongue weight to the axles on the tow vehicle and the axles on the trailer. Trailer tongue weight should be 10 to 15 percent of the loaded trailer weight.
F
Fifth Wheel Trailer - A trailer with a raised front that extends over the bed of a pickup truck. A special hitch is mounted in the bed of the truck , over the rear axle, to tow a fifth wheel trailer.
Filon - A type of fiberglass sheeting used on RVs with fiberglass sidewall construction.
Fiver - Another term used for a fifth wheel trailer.
Folding Camping Trailer - Also known as a pop-up or tent trailer. They are the smallest of RV’s with collapsible ends and sides for ease of towing and storage.
Fresh Water Fill - An opening on the outside of the RV where you can fill the fresh water holding tank with potable water to use when you are traveling or dry camping.
Fresh Water Holding Tank - A tank mounted under or in the RV that stores potable water for use while traveling or dry camping. To pressurize the system and use the water in the holding tank you turn the 12-volt demand pump on.
Full Hook-Up - A full hook-up means you connect the RV to the campground electric, water and sewer facilities. In addition to this it can also include cable TV and phone line connections.
Full-Timers / Full-Timing - Terms used for RVers that live and travel in their RV full time. Some full timers sell everything and live in their RVs 100% of the time. Other full timers that spend the majority of their time on extended RV trips choose to maintain a house or residence they can return to in between trips.
G
Generator - Commonly used on motor homes a generator produces 120-volt AC power. A generator allows you to use 120-volt appliances when you are not plugged into an external electrical source. Generators are rated in kilowatts. For example a 5 KW generator is 5,000 watts.
Genset - A short term for a generator set.
Gray Water Holding Tank - A tank mounted under the RV that collects wastewater from the sinks and shower. When you dump or empty your holding tanks you should always dump the black tank first, and then dump the gray tank. This will assist in rinsing out the flexible sewer hose.
Gross Axle Weight Rating (GAWR) - Is the maximum allowable weight that an axle is designed to support. The tow vehicle and trailer each have GAWRs.
Gross Combined Weight Rating (GCWR) - The maximum permissible weight of the tow vehicle and trailer combined when both are fully loaded for travel.
Gross Vehicle Weight Rating (GVWR) - is the maximum permissible weight of the vehicle when fully loaded for travel. The tow vehicle and the trailer each have GVWRs.
Gross Vehicle Weight or Gross Trailer Weight (GVW) - This is not a rating; this is the actual weight of the tow vehicle or trailer when they are fully loaded for travel.
This list is not all-inclusive, but if you learn these terms you will soon be understanding RV terminology.
Happy Camping,

D
Deep Cycle Battery - Often referred to as the auxiliary battery(s) or house battery, it is used to supply 12-volt DC power to the appliances and accessories in the RV. Unlike an automotive starting battery they are designed to hold a charge longer and be discharged repeatedly. The RV battery(s) is charged when the motor home is running, or in the case of a trailer, when the tow vehicle is running, if a charge line was wired in to the trailer plug. It is also charged when the RV is plugged in to a 120-volt power source and by an onboard generator.
Delamination - When the filon, (fiberglass panel) separates from the luan backing used to construct fiberglass sidewalls on an RV. This is usually caused by water damage.
Demand Water Pump - The onboard water system that operates off of a 12-volt demand pump. When you have potable water in your fresh water holding tank and the pump is turned on it pressurizes the onboard water system. When you open a faucet and the water pressure drops the pump cycles on and off to maintain a constant pressure.
Diesel Pusher - A motor home with a rear mounted diesel engine. Often times referred to as a pusher.
Dinghy - A term used for the vehicle you are towing behind the motor home.
Dry Camping - Camping in an RV without any utility hook-ups (water, electric, sewer). You can still use all 12-volt appliances and accessories as long as the deep cycle battery(s) has a charge. You can also use the onboard water system with the 12-volt demand pump and if you have a generator you can use the 120-volt appliances and recharge the auxiliary battery(s). This is what makes an RV fully self-contained.
Dry Weight - Dry Weight (DW) or Unloaded Vehicle Weight (UVW) is the actual weight of the RV as built at the factory. The DW does not include passengers, cargo, fresh water, LP gas, fuel or after market accessories.
DSI- Direct Spark Ignition (DSI) - is a system used to ignite the burner on a propane appliance with the touch of a button. It is commonly used on RV refrigerators, furnaces and on some water heaters.
Ducted A/C and Heat - When the A/C and heat is supplied throughout the RV using a ducting system. A/C is ducted in the ceiling and the heat is ducted in the floor.
Dually - A pickup truck with two tires on each side of the rear axle.
Dump outlet - Where both holding tanks terminate into one main outlet. This is where you connect the RV sewer hose to dump or empty the gray and black water holding tanks.
Dump Station - An area designated and approved for dumping or emptying your gray and black water holding tanks.
E
Electric brakes - Trailer brakes are electric and are activated when the tow vehicle brakes are applied by means of a brake controller installed in the tow vehicle.
Empty Nester - When all of the children are finally out of the house.
Equalizing Hitch - An equalizing hitch, or weight distributing hitch uses additional hardware (spring bars and brackets) to distribute a percentage of the trailer’s tongue weight to the axles on the tow vehicle and the axles on the trailer. Trailer tongue weight should be 10 to 15 percent of the loaded trailer weight.
F
Fifth Wheel Trailer - A trailer with a raised front that extends over the bed of a pickup truck. A special hitch is mounted in the bed of the truck , over the rear axle, to tow a fifth wheel trailer.
Filon - A type of fiberglass sheeting used on RVs with fiberglass sidewall construction.
Fiver - Another term used for a fifth wheel trailer.
Folding Camping Trailer - Also known as a pop-up or tent trailer. They are the smallest of RV’s with collapsible ends and sides for ease of towing and storage.
Fresh Water Fill - An opening on the outside of the RV where you can fill the fresh water holding tank with potable water to use when you are traveling or dry camping.
Fresh Water Holding Tank - A tank mounted under or in the RV that stores potable water for use while traveling or dry camping. To pressurize the system and use the water in the holding tank you turn the 12-volt demand pump on.
Full Hook-Up - A full hook-up means you connect the RV to the campground electric, water and sewer facilities. In addition to this it can also include cable TV and phone line connections.
Full-Timers / Full-Timing - Terms used for RVers that live and travel in their RV full time. Some full timers sell everything and live in their RVs 100% of the time. Other full timers that spend the majority of their time on extended RV trips choose to maintain a house or residence they can return to in between trips.
G
Generator - Commonly used on motor homes a generator produces 120-volt AC power. A generator allows you to use 120-volt appliances when you are not plugged into an external electrical source. Generators are rated in kilowatts. For example a 5 KW generator is 5,000 watts.
Genset - A short term for a generator set.
Gray Water Holding Tank - A tank mounted under the RV that collects wastewater from the sinks and shower. When you dump or empty your holding tanks you should always dump the black tank first, and then dump the gray tank. This will assist in rinsing out the flexible sewer hose.
Gross Axle Weight Rating (GAWR) - Is the maximum allowable weight that an axle is designed to support. The tow vehicle and trailer each have GAWRs.
Gross Combined Weight Rating (GCWR) - The maximum permissible weight of the tow vehicle and trailer combined when both are fully loaded for travel.
Gross Vehicle Weight Rating (GVWR) - is the maximum permissible weight of the vehicle when fully loaded for travel. The tow vehicle and the trailer each have GVWRs.
Gross Vehicle Weight or Gross Trailer Weight (GVW) - This is not a rating; this is the actual weight of the tow vehicle or trailer when they are fully loaded for travel.

Gas Prices
I don’t know about you but I don’t understand gas prices. Just last week crude oil closed under $34 a barrel, but the national average for a gallon of gas rose to $1.95. Crude oil drops and gas prices rise, what’s up with that? I read an article last week that stated because Americans weren’t buying enough gasoline (and suppliers weren’t making enough revenue) refineries concentrated on refining heating oil rather than gasoline, thus driving the price of gasoline up.
This week I read another article saying that the benchmark for crude oil prices is West Texas Intermediate, and because of the recession U.S. crude oil storage facilities are loaded up with gas resulting in the price per barrel being at a five year low. So why is the price at the pump going up instead of down? The article went on to explain that most of the crude oil going into gas in the U.S. comes from overseas, so gas prices at the pump will continue to go up. They are predicting $2.50 a gallon before spring is here. They blame this on the fact that foreign oil, in some cases is $10 more a barrel than it is in the U.S. right now. But can $7 or $10 more a barrel, when prices are at a five year low, keep driving the price at the pump up? I personally think we are getting ripped off!
I thought the one gold lining for Americans, during this economic downturn, was going to be lower gas prices. We didn’t even get to take the RV out since gas prices started to fall and now they are going back up.
I want to know what happened to the basic law of supply and demand. This is Economics 101. The supply and demand model states the price of a product is determined when the quantity supplied equals the quantity demanded. When there is a surplus in supply the price should be lower, not higher, to sell the surplus. The law of demand basically says the higher the price of a product the less people demand it, so why would they continue to raise the price when the demand is already low. The only reason I can see that fuel prices at the pump would rise when the demand is low and there is an overage in supply is for greedy suppliers to increase their revenues.
I guess $2.50 a gallon is better than $4 a gallon, but I wish there was a way that we, as a nation, could demand an answer as to why it is $2.50 a gallon when it should be $1.50 a gallon or less. Maybe we should start a national consumer coalition called “WE Demand to Know” questioning some of the things that go on in this country. I’ll bet if 100,000 or better yet 1,000,000 voices asked the same question our elected officials would realize we, the working class Americans, do exist after they are put into office.

The Lighter Side, 10 things you should NEVER do with your RV!
Ten things you NEVER do with your RV. Some of these are just plain old common sense, some you learn the hard way and some… well; you just don’t do it with an RV!
10) While traveling on the interstate in your RV floor it to see what your top speed is.
9) Assume you can fit under that two lane road bridge that doesn’t have the height posted.
8) Wait until next week to winterize the RV when the current temperature outside is 15 degrees.
7) Attempt to empty the holding tanks when your sewer hose almost reaches the drain outlet.
6) Loan your new RV to your best friend for a week. You may be looking for a new best friend!
5) Back the RV into the campsite hoping there is nothing behind you.
4) Take your 35 foot RV on the scenic mountain parkway where the posted sign reads no RV’s over 25 feet allowed. Trust me on this one!
3) Take your brand new RV on a hunting trip with all the guys, trust me on this one too!
2) Believe the RV salesman who says, you’re truck can pull anything on this lot!
And #1 if you read “My First Real RV Adventure” article on the rv.net blog you will remember when you’re camping in bear country you never put your trash bags outside the camper door!
Can you add anything to the list?
Happy Camping,
