We find Fly'n Js have the most maneuver room, and most have an RV island with both gas and diesel. No gas in the truck lanes. Pilots unless very new seem to have the least room. We like Loves most of which have plenty of room and McDonalds. We also like Speedways that have truck lanes because they usually are not busy and the pumps turn on with any credit card. Be aware that many truck lanes will not turn on the pumps without a dedicated fuel card. You'll have walk into the fuel desk to give them a credit card. However, this may have changed lately--we haven't used truck lanes other than speedway for some time.
