It's been struggling to get above zero in Wisconsin these last few days. I haven't noticed any trouble with mine in cold weather, but I have a #1, so smaller box to heat up (but also smaller element). Your smoker does look well-loved. I would definitely look into replacing your element with a larger one, if yours is an older model with the smaller element. I don't think it's difficult to do. Maybe order a new knob too while you are at it (you might need to call Steve for this.) Lots of parts are replaceable on these smokers, so they really last.
