Did two butts and eight racks of baby backs on Sunday. This was my first for ribs and came out great. Question, The butts took over ten hours, low and slow and pulled at 190. Wrapped and let sit. Perfect. I have a sfb and I have to keep lump or wood to keep it up to temp. Do I need a different type of smoker to let it go all night without touching it. The sfb I have to keep adding and watching. Thanks for all your help.
