Well, because you'll have to do them in batches, how will you hold them?
Wrap and put in an igloo, cambro? Remember when you do that, there will be so much heat they WILL continue to cook, so I tend to undercook mine just a bit.
If you're using the rib racks, I know it's a pain, but I like to rotate mine, front to back if I can, to even out the cooking. On mine, the back left is the hot spot.
I'll sometimes move top to bottom too
What else?
