Frequently Asked Questions

Q: How much does it cost in fuel for an RV road trip?

Q: How do I calculate the gas cost for a cross-country RV trip?
A: Enter your total trip distance, your local gas price, and your RV's fuel economy (MPG or L/100km) into the calculator above. For a cross-country trip, you can find total distances using a mapping tool or download the Roadtrip app which calculates route distances automatically.

Q: Why do gas prices vary so much from state to state?

Great app
My estimates for how much I have spent on petrol for various trips match closely with the app estimated trip costs. Quite eye opening comparing my son’s Holden Colorado $342 Wellington round trip to our Prius same journey $82.
