Expert Tips to Maximize RV Fuel Efficiency
Optimal Driving Speed
Maintain 55-65 mph for best fuel economy. Every 5 mph over 60 mph reduces efficiency by 7-23%.
Weight Management
Every 1,000 lbs of extra weight reduces fuel efficiency by 2-4%. Pack only essentials.
Maintenance Matters
Proper maintenance can improve fuel efficiency by up to 15%. Keep up with regular service.
Route Planning
Avoid steep grades and heavy traffic. Plan routes using RV-specific GPS systems.
Aerodynamics
Close windows, retract awnings, and secure external items to reduce wind resistance.
Climate Control
Use dash air conditioning at highway speeds instead of opening windows to reduce drag.

Frequently Asked Questions
How accurate is this RV fuel calculator?
Truck stops are generally better for RVs due to wider lanes, higher clearances, and pull-through access. They often have competitive prices and better facilities. However, compare prices as some regular stations off the highway may offer lower costs.
How much should I budget for fuel on a cross-country RV trip?
For a typical 3,000-mile cross-country trip, budget $1,200-$2,400 depending on your RV class and current fuel prices. Class A motorhomes will be on the higher end, while Class B vans will be lower. Always add 15-20% contingency for unexpected costs.
Is diesel or gas better for RV fuel economy?
Diesel engines typically offer 20-30% better fuel efficiency than gas engines, especially in large RVs. However, diesel fuel costs more per gallon. Diesel also provides better torque for hills and towing, making it ideal for Class A motorhomes.
How often should I plan fuel stops during RV travel?
Plan to refuel when your tank reaches 1/4 full rather than running near empty. This gives you flexibility for route changes and ensures you won't be forced to use expensive or inconvenient stations. For trip planning, estimate stops every 200-400 miles depending on tank size.
