I was thinking the exact same thing... with all the TEMP issues guys are having on this site, with probes being used to double check the internal smoker temp against what is being recorded by that one standing probe off to the side recording who knows what, I'd say why not a dial thermometer... I buy very accurate ones and pay top dollar for them when I built UglyDrum smokers and rehabbed other smokers... I mean what would or could it hurt!!!I am thinking top of the door, but should it go in the middle or closer to the smoke stack. My thinking is that the thermometer for the temperature control is on the left side, so the dome thermometer should go on the right.
