I've wore three Capri's out, over the last 15 years, and used a set of jacks that I built specifically to remove the campers from my trucks. I always run duallys, so the jacks needed to be able to stand wide enough for the fenders to clear, but still catch the underside of the camper. My last Capri was a Rodeo Delux with a large overhang. I had to place the jacks way forward on the camper to balance it. It's a pretty precarious job doing this, and always have at least one helper. Oh... . Never unload in the wind. Don't ask me why I know.....
I used 2 X 2 X 3/16 square tubing for the upright, 3 X 3 X 1/4 angle iron for the feet. I used a worm drive hand crank winch that I welded to a 2 1/4 X 2/14 slip sleave over the 2 X 2 upright. I ran the cable from the winch over the top through a pulley, and then back down to the sleeve. The worm drive insured that when you quit crankin' the thing wouldn't fall down or free-wheel.
I probably haven't done a good job describing my design, but cowboys all over would borrow them to remove their campers. They did a great job.
I could probably draw them up, if you want.
I loved all my Capris. I actually miss them sometimes. Now I've got a big living quarters gooseneck, and at times, I wish I still had the camper and bumper-pull instead; especially when it comes to paying for it. The Camper/bumper-pull set up is the cheapest way to get down the road.
