I have a Traeger, and due to limited room, I always use my rib rack. If I lay them on the grate, I can get 2 St Louis or 3 BB's. With the rib rack I have, I could do 8 racks of either. Since my philosophy, is to fill the smoker whenever I am smoking, I use the rack and usually smoke 6 racks of ribs. Ribs are just fine frozen and reheated to eat, and it makes it easy for my wife during the week, when I'm @ work to cook or warm up whatever she wants.
