^^^ I suggest purchasing multiple $4 oven thermometers and placing them around
on your cooking grate to determine if you have hot spots, etc. I've cooked on many
different types of cookers/smokers and my experience is that the exterior mounted
thermometer is always off by as much as 50 degrees depending on placement, some
high and some low. Once you learn the difference (yours, surface temp to outside
monitored temp) then you can rely on that thermometer, but not until then.
