Lighter, lower recreational vehicles can double gas mileage.
Q: My wife and I drive more than 20,000 miles a year in our recreational vehicle (RV), which gets about seven miles to the gallon, but high fuel prices are eating into our nest egg. Are there more fuel-efficient ways to enjoy the RV lifestyle?
– Walter Hendricks, Tampa, Fla.
A: Major RV manufacturers all report a downturn in sales since the price of fuel started to skyrocket a few years ago. A typical gasoline-fueled RV gets between 5 and 10 miles per gallon, and those who may have bought one to save on lodging and food on their travels are finding that filling ’er up may cost more than hotels and restaurants.
But as elsewhere in the auto and truck industry, some RV manufacturers are scrambling to incorporate gas-saving features and design new models with better mileage and a lower carbon footprint.
According to the website RV.net, several factors contribute to a greener RV. First is reducing weight by using lighter materials and improving structural design. Smaller RV engines also reduce fuel consumption (and weight) – if owners can live with less horsepower. More efficient transmissions, better aerodynamics, and increased nonpowered engine cooling round out the suggestions on RV.net.
Some of these features can be found in the new Avanti line of RVs from Indiana-based Damon Motor Coach, which offers a 70 percent or more increase in fuel economy over other large (Class A) RVs.
Damon converts the ultraefficient chassis, engine, and transmission of a leading parcel delivery fleet truck (delivery companies optimize fuel efficiency) into an RV. The Avanti’s chassis also sits lower than that of other RVs, for less wind resistance. Result: 14.5 miles per gallon, twice that of other RVs in its class.
