If you’re not using the Open Roads RV program yet, you’re missing out—big time. We’ve been saving some serious cash with this one, and it’s a no-brainer. The best part? It’s totally free. With Open Roads, you can save up to 75 cents per gallon of diesel, though we’re averaging around 30-40 cents off per fill-up. Not too shabby, right?

How it works: Open Roads negotiates discounts at truck stops nationwide. Unlike other apps, prices are updated several times a day, ensuring accuracy. You can check both the regular price and the discounted price before pulling in, which makes it easy to find the best deal.
