After looking at it some more, I am pretty sure that I am right about what it is.
I can almost agree, but first I need to dig mine out and double check.
I know within 5 feet where mine is parked, and I can find the 2 foot+ diameter wheels real easy, they're tucked in the rafters along with the base board.
Sure be nice if he'd wipe the label off and shoot a good pic of it.
