You always have to remember you can't back up towing 4 down. So you need to use bigger not full of vehicle fuel stops. If you plot the fuel stops before you travel you will know where the big ones are. Pilot has a discount through Good Sam/Camping World with discounts on fuel and dump stations that are right at the pumps. They are locked and you just go in and get code after paying to use dump station. You use the Pilot card first then the payment card, of which there are some credit cards that give as much as 5% off and 0% interest for up to 18 months. Just don't miss the monthly payments or they stick you with late fees up to $35. So with both used you can get fuel cheap. Good idea is to never go below 1/4 tank, as the generator will not run under 1/4 tank as a safe guard to not strand you without gas for the RV.
