Damn that is awesome!! It looks like you used a propane tank? I built one out of an old diesel tank and an old woodstove. It allows me to cook on the woodstove and smoke/grill at the same time. I put 11 whole chickens, two hog rear quarters, two racks of ribs and a couple dozen bratwurst on it at the same time, but mine is no where near as pretty as yours. If you built that, you did do a helluva good job!
