Here are some pics from the last time the wife and I cooked for a big crew, I believe we had 23 to feed. We smoked 2 briskets and a wild hog shoulder and did the rest in the dutch ovens. Not much you can't cook with a little practice. We always have a big fire that we pull coals from as needed. These pics might give you some ideas.
Preheating the lids is a good idea
Double rack for biscuits works really well, the rack fits right down inside a #14 deep sided oven
Salmon patties are always on the menu
