My 2013 Georgetown's automatic leveling jacks must be pretty smart because they so far have not twisted the frame and jammed the doors. I think the system senses the ground as soon as the jacks touch and keep the lift heights equal among the side and end jack pairs; even with the wheels lifted. I have however noticed the doors jamming when I have not used the jacks. It seems to happen after a period of time when I do not empty the tanks. Perhaps it's due the tanks filling unevenly.
