Harbor Freight and JC Whitney has the dolly's you put under car tires so you can roll them around ur garage, How about that?
they're called GoJacks and are great little devices, we use 'em all the time to maneuver full size vehicles around in the shop and for the paint booth...
I think this is a far better solution than the "cargo bed" as it is a lot less hassle and doesn't take up the floorspace when you're not loaded...you're gonna break an ankle climbing around on that cargo thing, or somone's gonna fall off while it's extended.
this is the first hit in a search, so shop around for price (this is for 2) GOJAK 5000 - (Pair) Vehicle Dolly Caster System - 5000 Lb.
