On average, Class A motorhomes and Class C motorhomes can get between 6 to 12 miles per gallon (MPG), while smaller Class B RVs can get between 15 to 20 MPG. Towable RVs, such as travel trailers and fifth-wheel trailers, don't have engines and rely on the towing vehicle for their fuel efficiency. To maximize your RV's fuel efficiency, you can use cruise control on the highway, avoid heavy acceleration and braking, and make sure the tires are properly inflated.

As far as RVs are concerned, we have to drive it at a slow steady pace and that impacts the mileage factor.
Most RVs are designed to provide a balance between comfort and mileage. Newer models often have more fuel-efficient engines, which can help save on gas costs without sacrificing too much on comfort. My personal view is that if you are planning to take longer trips and spend more time in the RV, then comfort should be given priority. On the other hand, if you are planning to use your RV mostly for short trips or occasional weekend getaways, then you may want to prioritize on mileage.
Properly inflated tires can improve gas mileage by reducing rolling resistance. Check your RV's tire pressure regularly and make sure it matches the manufacturer's recommendations.
The mileage of an RV depends on several factors, including the type and size of the RV, engine type, driving habits, and road conditions. Generally, smaller RVs with diesel engines tend to be more fuel-efficient than larger gas-powered RVs. Hybrid RVs use both gasoline and electric power to improve fuel efficiency. Airstream travel trailers, known for their aerodynamic design, can help the get between 15-20 miles per gallon.
Turning off the air conditioner can increase your RVs mileage to an extent. This would be possible only if the weather outside is pleasant.
By driving your RV at a steady, moderate speed, you can increase its fuel efficiency and get more miles out of each tank of gas. To accomplish this, using cruise control is advised. To avoid traffic and reduce stops and starts, plan your itinerary. Check tyre pressure and fill to specified levels. By packing less or deleting superfluous goods, try to lighten the load on your RV. Your RV will run more effectively and use less fuel with regular maintenance.
The load factor should also be taken into consideration if you want to increase the mileage of RV along with other factors.
Towable RVs don't have their own engines, so their fuel efficiency depends on the towing vehicle. When choosing a towing vehicle, it's important to make sure that it has enough horsepower and torque to safely tow the RV and any additional weight, such as gear and supplies.
