Good Sam got my truck towed with the camper on as posted above. You can't get the camper off and leave it by the side of the road or wherever you are stuck! You can't put the jacks down in the ditch on one side!
If the truck won't move, how can you even drive it out from under the camper? The tow truck can't pull it that straight either. In our case he had to pull us at an angle to get back on the road.
Only question was the height if on a long bed to clear power lines and bridges, or to tow it back wheels down with a regular tow truck.
