Fuel-efficient RVs can keep you and your family traveling even when gas prices fluctuate. While motorhomes and travel trailers may be viewed as gas hogs, there’s a lot of variation within the industry, making it easy to find models that help stretch your gas mileage.
How much does it cost to fuel an RV? There’s no simple way to answer this question due to the variance in rig types and models. For pull-behind campers, some estimates show that towing reduces your vehicle’s gas mileage by as much as 30 to 40 percent. For motorhomes, gas mileage ranges from 8 to 23 miles per gallon. Then you need to factor in the tank size. Larger tanks cost more to fill up but require fewer stops.
With gasoline averaging between $2.50 and $4.50, and diesel averaging between $3 and $5, in recent years, it’s easy to see why fuel efficiency matters. However, even when gas prices aren’t at their peak, usage is a concern. Fossil fuel usage contributes to environmental pollutants and global warming, and there isn’t an endless, accessible supply of crude oil. Buying a fuel-efficient RV helps your wallet, as well as the planet.
Let’s take a look at important features to consider and some of the best fuel-efficient RVs.
Important Features to Look for in Fuel-Efficient RVs
Class
Class As and Class Cs are generally gas guzzlers due to their size, shape, and weight, while petite Class Bs have the best gas mileage, with some matching or beating typical SUVs or pickup trucks.
Fuel
When buying a motorhome, you’ll need to decide between gasoline- and diesel-powered models. While gasoline currently costs less per gallon, diesel vehicles usually get significantly more miles per gallon, and at times, diesel costs the same as or less than gasoline. The future of RVing will likely include more electric-powered options; however, few of these models are on the market today.
Weight
Heavier vehicles and trailers use more fuel. Aside from the obvious weight difference caused by size, weight is also affected by building materials. Manufacturers use terms like “ultralight” or “lite” in model names to signal that lighter or fewer materials are used in interior and exterior construction. And keep in mind that while slide-outs open up floor space, they increase weight.
Aerodynamics
Some motorhomes and travel trailers are distinctively boxy, while others are curved with lower profiles. Aerodynamics affects your gas mileage. Look for rounded front caps, which reduce drag.
