No, Pilot / Flying J is not the "hot topic" on these forums so much because they are RV friendly, they are "hot topics" because Good Sam has an affiliation with Pilot / Flying J. In other words, Camping World, Motor Home Magazine, Trailer Life, RV.net, Good Sam, Coast-to-Coast .... all belong to the same parent company. Pilot / Flying J also have an affiliation, thus the reason for the Good Sam discounts at the pumps. I think that's the REAL reason Pilot / Flying J are discussed so much on these forums.
I don't do truck stops, and not just Pilot / Flying J. But smetimes, occasionally, am in a position to use one. I still don't like them. But when I have used them, the car pumps have always been convenient for RV's and not near as dirty and grimy as the big rig truck pump bays.
Now, there is only 1 truck stop that my wife insists on stopping at whenever we pass there. If we don't stop, get out, and visit the shops inside, I NEVER hear the end of it. We do usually plan on getting diesel there, and we do use the car pumps, and that's the
Iowa I-80 truck stop (click here). This really is a pretty interesting truck stop. It's more than just a truck stop, it's a complete truck-stop, shopping mall and a museum all rolled into one!
