How much does fuel cost for a cross-country RV trip?
For a 3,000-mile cross-country drive at current 2026 fuel prices: Class A motorhome $2,000-$4,000. Class C $1,500-$3,000. Class B campervan $1,000-$1,800. Fifth-wheel + diesel truck combination $2,000-$3,500. Variability comes from real-world MPG, route choice, and current pricing. Plan toward the upper end of these ranges.
- Class A: $2,000-$4,000
- Class C: $1,500-$3,000
- Class B: $1,000-$1,800
- Fifth-wheel + truck: $2,000-$3,500

Budget reduction strategies
Drive shorter days. Real-world MPG is best at sustained 55-60 mph. Pushing 70 mph reduces MPG measurably.
Plan around state pricing. Filling in Texas + Oklahoma + Tennessee is dramatically cheaper than California + Oregon + Washington.
Use truck-stop loyalty programs. 5-10 cents per gallon adds up on a long trip.
Consider one-way rental drops. East-to-West and West-to-East one-way rentals exist but with surcharges.
What RV community + fuel pricing data doesn't tell you
Cross-country fuel realities are well-documented in the RV community but each generation of travelers seems surprised. Plan to the upper end and have margin.
Frequently asked questions
