Unless you are say, disabled, and would like to raise and lower the camper remotely: ... http://www.youtube.com/watch?feature=player_detailpage&v=lTCm_RQ8ySM .... Jump to 4:00 mark.They are very easy to crank, and thus I would think that no one would have need for an 'electric' one.
I have watched a large Lance being removed using remote electric jacks and it was fast and painless. I can see where an older fellow might want this system, even on a lightweight off-road camper.....
