I assumed he meant height. Obviously nothing is that short. 7' is a common height restriction for parking decks and what not.
OP, I am often able to back my 26'+ TC and crew cab truck into regular parking spots if you get one at the edge of the lot. I back in allowing the camper overhand and the truck bed behind the rear wheels to hang over the grass or landscaping around the parking lot. This effectively "lengthenes" the parking spot by a good 6 or 7 feet. It works great at fast food restaurants, shopping centers, grocery stores, etc.
