I had a purchase yesterday at RD. 18 pound packer,2-9 pound butts,and 3 racks of baby backs. Looking forward to a full UDS smoke this weekend. I am thinking putting the brisket and butts on the bottom rack and ribs on the top rack. Plan on smoking at 250. 2-2-1 on ribs and foiling brisket and butts at 160, then pulling when probe tender, wrap in towels in cooler for a few hours. Any other advise?
