I smoked five racks of baby backs a couple weeks ago in my # 3. I laid them 2 to a shelve, heck I could have easily done 8 racks total. I have to say they were my best ribs ever!! I smoked them for 5 hours straight. Used about 3 oz of hickory. The temp was set to 225 and I never opened the door, not even once. After five hours I placed them on the stick burner with straight charcoal added the glaze and finished them off for about another half an hour. Wow! I am impressed with this smoker!! Sorry guys I would have taken pictures, but there was no time. Imagine the best ribs you ever ate and that is what they looked like.
