My Dad and I built a cool storage cart for my doors while off my Jeep. We used some extruded aluminum I salvaged from a couple of rear projection racks at work. We had to make some nuts to go into the channels and purchase the casters. See in the photos.
Whoa nice work! I like that it looks kinda small too so that when you don’t have the doors on it’s not taking up a bunch of room. Well done!
