generally I'm smoking for 4 with (at the very least) the next lunch or dinner so call it 8 people. I started thinking #3 so I'd have lots of foodsaver packs of pulled port and brisket for quick meals that were also delicious, but I decided I'd just use the #2 more often with less leftovers (per smoke). I could see parties of up to 20, but I'm pretty sure I can make that work pretty easily in the #2 as well (brisket and BB then smoke ribs while those are resting)
