Do you unload you camper from truck when camping?

I'm pretty good backing up, and using my mirrors, which are really quite good on both of my trucks, especially the Super Duty F350 which I'll put the truck camper on, so unless there is something specific with loading/unloading the truck camper (is a dually going to make it harder, for example?) then I suppose it's mostly a "practice makes perfect" type of thing -- No?
