I need to store several very large objects vertically, because they take up a ridiculous amount of floorspace. Think: rooftop tent, cargo system, roof rack with accessories. The largest item is 60x80, The idea is, three shelves including the top, with at least 15 inches between them, each capable of holding at least 300# and preferably more, with the whole thing on 6-inch casters.
Looking for suggestions on a good strong design for this. Will need to be pushed around a fair bit, so it can't be flexy. Clear (unimpaired) shelf dimensions 96x 72, with legs outside of those measurements. I'm assuming it will be a lot cheaper to do this in wood than to buy pallet racking and hire a welder. Thanks for any help!
