Can you do on a UDS at the same time? I've done 2 around 7 to 8 pounds each. Can you fit 4 of them on the main rack or is that pushing it? Do I need a second lower rack? I'm thinking of doing pulled pork sammies for around 80 in a month or so. Trying to figure out if that's a one time shot or a couple days effort. I only have one drum. How much do you need to start with per person? I figure if they "pig out", I'll need a half pound each precooked weight. If so, that may be more like 5 or 6 butts in the 7 to 8 pound range. 3 and 3 on two racks? That's 6 at a time. Somewhere in there is overload.
