See my post on the AT camper thread. If you don't have any weight on the roof, like I do in the winter, besides snow and a solar panel, a cam strap makes this a 2 minute 1 person ordeal. Really easy peazy.
Hook one end over the roof lifter bracket thingie, and cam it down anchored off the sheet metal on the wheel well. So simple. If you want to get fancy, hook the other one (they always come in pairs) on the opposite corner, and you are adding a whole minute to the perceived mess.
It just refuses to beat crouching down in the camper, using your head and your thighs to squat a roof up. Now it just pops up, and on deflation mode, gives you a bit of time to check that the corners are tucked in, and well, you're done.
Can't say enough about it.
