Fuel prices continue to fluctuate, but there are a few strategies you can try to protect your wallet.

During times of rising fuel prices, RV owners may be quick to ponder whether such scenic travel continues to be affordable. RVing is a lifestyle choice not always driven by fuel prices, but visiting a fuel pump regularly is an RV fact of life.
We’ve all felt the impact that higher costs have had on driving any type of motorized vehicle, let alone a large motorhome or some type of RV towing configuration. But it’s hard to negate the fact that no matter how much fuel prices rise, many RVers are not willing to give up on RV travel. This is especially relevant today, as we have experienced the grip of record-high fuel prices.
It’s not all negative news, by the way. There are a number of things owners of all types of RVs (gas or diesel, motorized or towable) can do to combat higher fuel prices. Most likely, seasoned RVers already are aware of some of the ways to improve fuel economy, but these four are worth repeating.
Simply Slow Down
When oil prices rise, discussion begins among governmental and special-interest groups about reducing the speed limit on all highways to 55 mph. I often drive at this speed, but only when I can stay out of the way of faster-moving traffic. Although this may seem extreme, especially for interstates and freeways, the physics actually make sense. Increased speed uses more energy and, therefore, more fuel to overcome greater air resistance. The relationship is approximately a 3:1 ratio. So, for every 5 mph over 60, fuel economy drops roughly 8 percent for an average passenger vehicle — and even more for a motorhome or a tow vehicle pulling a large travel trailer or fifth-wheel, because of the substantially increased wind resistance.
Many believe that 55 mph is the appropriate speed to maximize fuel efficiency across the board. This, of course, depends on the specific vehicle, but slowing down is one sure way to improve fuel economy. RVers are encouraged to slow down anyway, if just to enjoy the scenic beauty!
Drive Shorter Distances
Another way to get the most bang out of each tankful is to drive shorter distances and spend more time at a single location. Why not experience the lifestyle closer to home rather than head out of state? Search for a comfortable RV campground that’s not far from home and spend some time there. In fact, many RVers reserve a seasonal site at a campground during the summer and visit it on weekends.
Inflate Tires Accurately
A lesser-known means of saving fuel, as well as maintenance costs, is to be sure all RV tires are inflated to at least the minimum stated air pressure. This is achievable only by knowing exactly how much weight each tire position is supporting. Tire manufacturers publish charts that list the minimum inflation required for every tire size by the load each will be carrying. It is important to note that the pressure indicated on the sidewall is the minimum psi to carry the stated maximum load and should not be viewed as a recommended pressure. It is highly encouraged that owners have each individual wheel position of their
RV weighed (using individual scales) by an RV-industry-recognized entity such as the RV Safety & Education Foundation (www.rvsafety.com).
Minimize Idling
When a combustion engine idles, the end result of the fuel consumed is 0 mpg — purely wasted fuel. Plus, it’s not beneficial to the environment. Turn off the engine when stopped or parked for any lengthy period.
While our record-high fuel prices are certainly on the minds of all who utilize motorized transportation, RVing continues to be one of the most cost-effective forms of travel, and certainly the most enjoyable. According to a 2018 CBRE Hotels Advisory study commissioned by the RV Industry Association, traveling in an RV saves a family of four from 21 percent to 64 percent versus the cost of any other form of travel. The determining factors include the size and type of RV. Although fuel prices were lower at the time, the study showed that, for instance, prices would have to rise to about $13 a gallon for a Type C motorhome vacation to be more expensive than the least expensive non-RV vacation.
Fast forward to today. It’s likely that this data remains largely unchanged, considering how the rising price of fuel has affected the cost of other forms of travel as well.
So, keep these tips in mind, but don’t let high fuel prices temper the excitement of traveling the scenic highways of North America.
