⛽ RV Fuel Cost Estimator
Calculate fuel costs for your RV trip using real MPG data from 50+ rentals
How to Use This Calculator
Fuel is often the second-largest expense on an RV trip after the rental itself. A Class A motorhome getting 7 MPG will cost nearly three times more in fuel than a Class B camper van getting 16 MPG over the same distance. This calculator uses real-world MPG data from our rental testing to give you accurate fuel cost estimates and help you compare costs between RV classes.
1. Select RV Class: Choose the type of RV you're considering. Each class has significantly different fuel economy.
2. Enter Trip Distance: Input your total round-trip mileage. Use Google Maps to plan your route.
3. Adjust Gas Price: Enter current gas prices in your area or along your route.
4. Compare Options: See how fuel costs differ between RV classes to find the best value for your trip.

- Class B: 14-18 MPG (best fuel economy)
- Class C: 8-14 MPG (moderate)
- Class A: 6-10 MPG (lowest fuel economy)
- Travel Trailer: 12-16 MPG (with tow vehicle)
💡 Fuel Cost Examples
1,000-mile road trip at $3.50/gallon:

📊 Factors Affecting MPG
- Terrain: Mountains reduce MPG by 20-30%
- Speed: 65 MPH vs 55 MPH = 15% worse MPG
- Weight: Full tanks/gear reduces MPG
- Wind: Headwinds significantly impact larger RVs
- AC Usage: Running AC reduces MPG by 5-10%
💰 Fuel Saving Tips
- Drive 55-60 MPH (RVs aren't aerodynamic)
- Plan routes avoiding mountains when possible
- Keep tires properly inflated
- Don't overfill fresh water tanks until destination
- Use cruise control on flat highways
- Consider shorter, basecamp-style trips
