I sort of do this as well. I have my hardtop standing in the storage closet in my garage, and I lean the doors underneath that. All are on cardboard.Lean em against the garage wall on top of some cardboard and run some bungee cords to two eye bolts in the wall to "secure" them from falling. I'm lazy...many better more thought out solutions others will offer I'm sure. Congrats on the jeep !!
