Look for stations with pump lanes parallel to the main road. When you get close, pay attention to the exit...sometimes you can easily get into a station but you cannot get out as easily. Also watch the approaches. A few months ago we pulled into a station and my only way out was down a steep hill and I drug the back end of the camper. Most of the modern chain stations are being built with trailers in mind so don't worry to much. You may want carry 5 gallons with you but beware the new fuel jugs have a mandated valve on them that maybe difficult to use on your truck. I wasted $20 on a jug from Wal-Mart that I cannot use in the filler neck of my Silverado.
