I have a cabinet style stainless propane smoker(Cabelas brand). I use Royal Oak lump and wood chunk and chips. I'm having trouble getting my spares to temp. I'm hovering at around 200 degrees and can't get higher. Tried opening dampers, tried closing dampers. There's not much wind and the outside temp is in the 60's. First of all, what can I do to get temps up? Secondly, if I can't get them up will my ribs (3-2-1) suffer?
