I recently bought a horizontal offset smoker that came with an adjustable convection plate in it. It does a really good job of keeping the temps even from side to side and buffering changes when I open the door, add more wood, etc. Anyway I've been reading some threads on here about water pans being primarily used for this same purpose and for keeping the air moist in really dry climates. I live in a dry area but nothing like Arizona. I have had no problems with my food drying out in the smoker so I'm wondering; should I be concerned about this or is this just splitting hairs?
