I have been using Flying J for 15 years as dedicated as I can be . On my last trip 5000 miles I had to use whatever diesel stations available .they were cheaper ,faster ,They would just turn the pump ...
I also use to stop at FJ but the RV lane was always occupied and many times the RVer's would be inside for a long time or waiting for propane and then using the dump station. I just don't have the patience to wait 30/40 minuets for my turn, I just want to gas up and go.
