How much fuel will an RV use on a trip?
The RV Gas Mileage Calculator helps recreational vehicle owners estimate fuel consumption for road trips based on distance, fuel used, and tank capacity. RVs have some of the lowest fuel economy ratings of any passenger vehicle, so accurate planning prevents budget surprises.

How it works
RV Gas Mileage Calculator: inputs, formula, and result
This tool calculates the specific MPG of recreational vehicles by taking the distance traveled and dividing it by the massive volume of fuel required, yielding the low efficiency numbers typical of RVs.
Formula
RV MPG = Distance (miles) ÷ Fuel Used (gallons)
Worked example
Traveling 600 miles on 60 gallons gives 600 ÷ 60 = 10 MPG.
Pro tip: RV fuel economy drops sharply in headwinds and on mountain passes. Budget 15-20% extra fuel for routes with significant elevation changes.
Personalized guidance
What changes the result for RV Gas Mileage?
RV mileage changes drastically depending on the towing weight of a secondary vehicle, the bluff aerodynamic profile, water tank fill levels, and mountainous driving routes. Traffic, tire pressure, vehicle load, terrain, driving style, weather, fuel price, and the quality of the input data can change the final result.

FAQ
FAQs about RV Gas Mileage
3 questions
Question 1 of 3 is open
What MPG do most RVs get?
Class A motorhomes average 6-10 MPG, Class C motorhomes get 8-14 MPG, and Class B campervans achieve 15-22 MPG. Towable trailers reduce the tow vehicle's MPG by 30-50%.
How far can an RV go on a full tank?
With a typical 80-gallon tank and 10 MPG, a Class A RV can travel about 800 miles between fill-ups.
Does RV generator use reduce driving range?
The RV generator runs on the same fuel tank. A generator typically uses 0.5-1.5 gallons per hour, which reduces your total available driving range.
