I have a 11ft 6 in. camper that stays on my truck...primarily because it's such a hassle to remove it, and a lack of trust of the manual jacks. It can be dangerous to remove your camper on unlevel or soft ground. They can topple over easily or rip off the corner. With the newer electric jacks, you have it easier to put the camper on or off, but the safety issues are still the same. I think campgrounds that don't allow removal of a camper have probably run into legal problems when someone topples their camper and tries to blame the campground for unlevel or soft ground.
