Unless you are traveling the back roads it is fairly easy to hit the Flying J's, Pilots, Petro's, and Love's. I mean you can't drive 10 miles with out seeing a billboard telling you where the next exit is for one of those. Since we have the discount card for Flying j/Pilot that is where we always stop and never have a problem finding one. Or you can to on to their websites and pull up maps with their locations......I use the truck side pumps if I have to but prefer the RV pumps because they seem to have a lot less fuel spilled on the ground. Hate stepping out of my truck into diesel fuel......
