I enjoy my propane Masterbuilt smoker but it is very difficult to use at the low temperatures needed for smoking. To get down to 225 degrees in the Colorado winter I have the vents wide open and the large door cracked with the gas at minimum. (That's when it is windy and 28 degrees.) I lose a lot of good clean smoke through the door but otherwise it is too hot for good smoking. The thermometer on the front of the smoker is worthless. Replace it with a Tel-Tru BQ300.
