we're 56-57' overall length (Class A gasser + Jeep SUV). our first option for fuel is Flying J as virtually all of them (other than franchise stations) have two RV lanes with gas and diesel. every now and then we encounter a car or pickup blocking the lanes but usually tbe wait is short. if the lanes are tied up and the station is not busy we'll use one the 'car' lanes preferably one of the end pumps. option 2 is another truck stop...Pilot, Loves, Travel Centers,etc. option 3 is a "regular" gas station preferably with pump lanes parallel to the street or with a set of pumps adjacent to a side entrance. it's usually not a major issue to find gas.
