Jeezus, I've been piecing that together in my mind for my truck cap and Early Bronco top for the past few weeks.This could enable you to drive out from under your roof as well...leaving it standing until such a time as you want it back on...then you just back up under there again and lower it back down into the truck.
That's one of the ways I set up to remove the camper shell on my truck (also have a hoist in the shop).
