I have an idea for a useful project to save my aching back. I would like to rig a pulley and sling system from my garage ceiling that would enable me to easily lift my fifth wheel hitch out of the bed of my truck. Once the hitch is raised off of the bed, I can pull forward and lower it onto a rolling dolly on the garage floor for storage. You would simply reverse the process to load the hitch back in. Has anyone ever done anything like this before and if so, are there pictures or plans? Thanks!
