I saw a cooker similar while in Columbia last weekend. It was a half keg cut in half. Could fit in the square hitch on bah of truck. He said it was originally charcoal but a lot of the tailgate places banned charcoal because people would dump out hot coals, so he converted it to gas. Pretty cool for grilling at tailgate. I love the fact it was home made and customized to fit his needs.
