With my Leer cab high canopy, I installed a Yakima rack system on the canopy. Then in the ceiling of my garage, I put up 4 eye bolts. I lift the canopy off the truck with 4 rachet type tie downs - placing one on each corner of the Yakima rack. It hangs from the ceiling until ready for reinstalling. Then I simply lower it one corner at a time onto the truck. I have done it this way for years with no adverse effects.
