I am replacing the floor in my 15 foot camp trailer. I have removed part of the old and have the body supported with blocks so it doesn't sag. I need to remove the blocks so I can install the new ply. I have a cherry picker (engine hoist) and atached it to the spare tire carrier. As I jacked up the picker arm, the body started to pull away until it stoped at the rear bumper. If I go another 1 inch it will clear the bumper and possibly tear the sheet metal. Obviously this will not work. I have thought about screwing through the trailer wall and sandwiching it between 2 pieces of 2X4 and lifting the body with that. It would spread the load out and prevent it from pulling away and possibly tearing. The down side it that I would have to repair the holes. I would appreciate any and all input.
p.s. I could put the wood on the back and keep it there as an accessory of some sort.
