RV Miles per Gallon

1. Class A Motorhomes

These are the largest RVs, built on commercial bus or truck frames. They usually get between 6 to 10 MPG, depending on weight, engine size, and towing load. Diesel pushers (diesel engines in the rear) tend to be a bit more efficient than gas models.

2. Class B Motorhomes (Camper Vans)

Class B RVs are the most fuel-efficient type. Since they're built on van chassis and are smaller, they typically get between 16 to 22 MPG. Some diesel versions can even reach the mid-20s.

3. Class C Motorhomes

These mid-sized RVs, which usually have an over-cab sleeping area, get around 10 to 14 MPG. They're built on a van or truck chassis and often use gasoline engines.

4. Travel Trailers

Because travel trailers don't have engines, MPG depends on the towing vehicle. A full-size SUV or pickup pulling a medium-sized trailer might get 10 to 14 MPG. Smaller trailers towed by crossovers or mid-size trucks could see 14 to 18 MPG.

5. Fifth-Wheel Trailers

These larger towables require heavy-duty trucks and usually get 8 to 12 MPG when towed. Diesel trucks used for this purpose can slightly improve fuel economy compared to gas trucks.

6. Pop-Up Campers and Teardrop Trailers

These lightweight trailers are easier to tow and cause less drag, resulting in 15 to 20+ MPG when pulled by efficient vehicles like crossovers or mid-size SUVs.

Factors That Affect RV MPG

• Weight: More weight means more fuel burned.
• Wind Resistance: Larger RVs act like sails on the road.
• Speed: Driving above 60–65 mph sharply reduces fuel economy.
• Terrain: Mountains and headwinds lower efficiency.
• Maintenance: Proper tire pressure, clean air filters, and regular engine servicing improve MPG.
