Got a 2 ton with all four casters / wheels that swivel, came from an outfit called "Tool City" many years ago in 'Vegas. Its worth its weight in cold beer even tho it doesnt fold up and takes up a lot of space. Used some plywood and made a shelf that works for storing jack stands/ whatever,it attaches to the legs, easily removed. Big jack slides under/ between the rails, works for me. Used it to pull bodies of off frames more then once.
