The gas mileage of Class C motor homes will vary by each brand and model. However, gas mileage typically ranges from 6 to 14 miles per gallon.
Keeping your speed down is one way to improve your gas mileage. Making sure your tires are properly inflated and that your motor home is not overloaded will also help to improve your overall gas mileage.
Keeping up with regular maintenance of your RV will help keep it running cleaner. This, in turn, helps keep your gas mileage in the upper ranges, helping you to get the most out of your gas money.
