Does anyone else have trouble maintaining temps on their Treager? My Lil Tex creeps up on me. Yes, I keep the fire pot clean and ashes vacuumed. When I smoked my bacon last weekend, I kept the controller set to "smoke" which is supposed to maintain at 160 degrees. It did that for the first hour, then began a slow climb to 190 by the end of the second hour, bringing my bacon to an internal temp of 150 a full hour quicker than I planned. I started my smoke in the evening when it was in the low 70s so weather wouldn't be a factor. Any ideas?
