Mine is just some eye bolts into the ceiling with rope through them. One end of the rope is tied through a hole drilled into the ends of two 2x4's. Then I tie a loop in the other end of the rope. I can drive the truck into the garage, lift the front & back of the top and slide the 2x4 under it from inside the truck. Then get out and lift each corner running the loop over the end of the 2x4. This lifts the top off the bed and I can drive out under it. Total cost was under $12.

If I could weld and had a taller garage roof, I'd love to have the setup BobbyK has.
