May have been said before in this thread--didn't research. I plan the day's fuel stops the night before using Allstays Camp & RV--well worth the $10 fee for me, but there used to be a free version that showed major stations only. It also shows Walmart stores for those that want to try to save a few cents on fuel. There is no doubt that the stations next to the Interstate highways are the most expensive, but I just pay it for the convenience. The miles shown on Allstays are low--must be as the crow flies. To get miles I use Google maps. I have to be careful of miles having a small fuel tank.
