I found two barrels that I could fit together for a double barrel UDS. This is what I came up with. I think it came out pretty good. I will try it out with a couple of 7 pound pork butts tomorrow. You can use two racks or hang the meat like chicken halves or ribs. You should be able to hang 12-15 chicken halves plus put a rack on for more. I also put in two prob holes, one for each rack
