Fueling at truck stops

We prefer Loves travel plazas because the auto islands are roomy and easy to navigate with our 27' fifth wheel while filling with Diesel. You can ALWAYS pay at the pump at the auto lanes, but rarely do I get it to work in the truck lanes even with the Sams club RV card, so 2 walks into the truck fuel desk--one before and one after. And, Loves will have a McDonalds or Hardys. Most Fly'n Js east of the Mississippi have RV lanes, but also the auto pumps are easy to navigate through. In our opinion, yours may vary, Pilots tend to be older with tighter auto lanes--we avoid Pilot. I plan the next day's fuel stops the night before using AllStays. They have a free version that shows major fuel service, but the "for $" version also shows Walmarts and campgrounds.
