Which Class Is The Most Fuel Efficient RV?

It’s possible to find more efficient RVs despite their class, but it’s unlikely. The RV class is a primary factor for overall gas mileage, including class A, B, and C RVs and motorhomes.

Class A

The Class A motorhome is larger and much less fuel efficient than any model. They are expected to get roughly 6-10 mpg, which is lower than all other RV types.

This is primarily because of their size and available features. They are equipped for longer journeys with massive fuel tanks to achieve long-distance riding without needing to refill and constantly make fuel stops.

Class B

Often referred to as camper vans, the Class B motorhome is the clearcut winner for adventurers interested in the best RV gas mileage. We can expect about 18-22 mpg, with some high-end models providing up to 25 miles per gallon.

This RV style also has a sleek build and compact sizing, so getting better mileage while traveling is much easier. Typically, the front end of this RV has a slant, so it’s more aerodynamic with less wind force and resistance to impact speed and vehicle drag.

However, this is not always an option for larger families. They cannot travel in a class B RV because there is less space and insufficient storage and weight capacity. But generally, this is the most fuel efficient class of RVs.

Class C

The Class C motorhome is more of a traditional RV. It tends to have a slightly lower average MPG, but this depends on the sizing and the model. The estimated industry average is 8-15 MPG.

However, there are some great options with enough sleeping space closer to 17-20 MPG. This is not the traditional gas guzzler RV and acts like a more fuel efficient travel trailer instead.

We have noticed the smaller sized models with diesel engines provide the better gas mileage too. This is not always the case with diesel vehicles, but this class gets great gas mileage.

Tips For Better RV Fuel Efficiency & Gas Mileage

Other than choosing one of these fuel efficient options, there are a few things to try on the road to help get the best mileage.

Using Cruise Control

Cruise control is typically available on all RVs and it’s a smart and savvy way to save fuel once we get on the highway. It’s estimated that cruise control saves 7-14% more fuel because the vehicle maintains a consistent speed.

Checking Tire Pressure

Next, check the tire pressure on the RV. Low tire pressure causes fuel to burn faster and it’s estimated that for every 1 PSI lost in tire pressure, the vehicle burns about 0.4 % more fuel.

It may not seem like a lot, but after a 3-6 PSI drop it can become significant. Fill up tires to the desired PSI levels before any long journeys.

Packing Lighter

The weight inside an RV will instantly impact handling, speed, and, most of all, the expected miles per gallon. For example, the new modern hack to save on fuel is to buy a fiberglass RV instead of an aluminum one.

Pack as light as possible to save on fuel, even though this is much easier for solo travelers than families. They are much lighter, meaning they use less fuel while driving. But the lighter an RV, the better the fuel efficiency.
