My plan, although I haven't tested it yet, is to put 4 "eyelets" in my garage ceiling. Then I will run 4 ropes down with hooks on the ends. The truck will back into the garage and have all of the hardtop bolts removed. Then 4 more eyelets will be placed in 4 bolt-holes in each corner of the hardtop. They will be mounted with big washers or maybe even strips of angle iron to prevent localizing too much stress. Then each corner of the top will be lifted, one at a time, and placed on a piece of 2x4 or 4x4. As the top sits there on the wood, the hooks will go into the eyelets. Then the wood can be removed and the top will hang there just an inch or two above the bed and the truck can be driven out.
Now a pulley (or pulley system) and tie-off point can be added to each rope and then the whole thing can be lifted right up to the ceiling, a little bit on each corner at a time. Just make sure it's secure before parking another vehicle under it (or walking under it)
