How Many Miles Per Gallon Do RVs Get? (5 Examples)

When it comes to finding the ideal motorhome for your journey, one of the big questions for many families is fuel efficiency. The expenditure on gas money can make a considerable dent in your budget.

Given the wide range of RV types available in the market, it would be wise to find out what the gas consumption of a motorhome is before making the decision to buy.

How many miles per gallon does an RV get?

Here we look at 3 three classes of RVs, and the Euro Motorhome. Average mpg is dependent upon their size:

  • Class A   7-10mpg
  • Class B   10-25mpg
  • Class C   8-12mpg
  • Euro Motorhomes 22-30mpg

Average fuel consumptions vary based on an RV’s size; in general the larger the RV, the lower the mpg. The other main consumption factors will depend on the terrain you are driving in and whether you are towing additional trailers or cars.

In this article, we will consider the different designs and classes of RVs available in the American and Europeans markets to find out their fuel consumption in miles per gallon.

The first thing to understand is that there are basically three primary classes of RVs; A, B, and C.

These range in size starting from the largest to the smallest in that order. The larger RV types have some of the least gas mileage whereas the smallest ones get some of the highest.

If miles per gallon are a big concern for you, then you may have to sacrifice some space and comfort by going for a smaller RV. However, if you insist on keeping your journey as comfortable as possible, there are still interesting options available for you.

How Do I Improve Gas Mileage on my RV?

If you are worried about how much fuel you’re consuming per mileage, there are things you can try to regulate the amount of fuel being used.

  • Pack light

If you want to keep the gas mileage down on your RV you should make sure to pack light.

If you add a lot of toys and heavy items to the RV It will definitely impact your mileage and fuel efficiency. So leave the dirt bikes and four wheelers at home unless you’re absolutely sure you’re going to use them.

  • Tires and Inflation Levels

Confirm that all the tires are inflated correctly.

This will not only improve the mileage but also enhance your safety. Check the manual to ascertain the ideal psi for your tires. Alternatively, check the sticker near the driver’s side door.

  • Smooth Driving

Desist from jackrabbit starts and train yourself to brake slowly when trying to halt the vehicle.

This will also guarantee that your passengers have a non-turbulent ride and keep things inside the cabin from moving around or falling over. The faster you accelerate your RV the more gas you will burn.

  • Air Conditioning

Some people are torn between rolling down the windows and turning on the air conditioning to manage fuel consumption. So which one is better?

I advise that you do both; open the windows when driving at lower speeds and turn on the AC when driving on the highway.

By opening the window you will also impact your fuel consumption in a good way.

  • Look For Discounts on Gas

Gas prices can vary a lot from state to state so make sure to check the price to fall your fill up the tank.
