Billy here.
This is a cage for a pallet tank with the pallet still attached, but the tank removed. OK, the technical name if you want to Google it is Intermediate Bulk Container (IBC).
This is a Goat Transport System.
It's just about that simple. I found a guy with some of these for sale. He had already removed the tanks. He sold me this and a piece of metal grating the right size to act as a gate ($20). The whole thing fits like this in the bed of a pickup. I put down a piece of plywood for a floor, and fasten the grate in place with wire and bungie cords.
