Well, that's always fun. If I get it just right there's a 2–3 inch gap between the bottom of the camper and the side of the truck tailgate. I did pretty good today without too much re-maneuvering. I need to get it about 3/4 of the way under the camper before I plug in the power, which is on the bed. Then I back it up the rest of the way, but not all the way. I leave a small gap in front or the camper presses on one of my tail light lenses. #RVing #RoadTrip
