We had a bunch folks over two weeks ago for our annual fall festival BBQ with the neighbors. We cooked 12 slabs of ribs ( I have cooked as many as 15 at one time ), two briskets, 4 pork shoulders and 48 chicken legs, over the course of 2 days.
Here is a photo of nine slabs of ribs on the rib rack and the other three top side. Everything was a hit.
