You only think you had a 'challenge'!
Try stuffing almost the same amount of equipment in a ONE car garage that has to be used by a female who is very picky about her car and garage! (no not wife!)
Everything I use is either on casters, a hoist, mounted to the joists or hinged to the wall!
One thing I will say though is it forces me to keep order and keep it clean!
Nice job on your solutions!!!
