A few years ago, I put up a couple of shooting houses by myself. The kicker was that both of them had a decent sized tree right behind where I wanted them. I took 150 ft of rope, secured it around and just under the roof line of the house, ran it around the tree as high as I could, ran the rope back thru the center of the rear and the front window, and then hooked the end to my trailer ball. I lifted the house at the roof to get it a little off the ground and put a couple of blocks under it. Then, eased forward in 4 wheel drive, low range and up they went. I was very careful to try to keep everything lined up straight. It surprised me how well it went.
