For those of us in cold weather ares, (And we've had plenty of that this winter) I've found it very difficult to maintain the temp in my smoker. Since I didn't want to wait until Spring for my next smoked ribs, I simply wrapped my smoker in some spare insulation and found it worked remarkably well when the outside temp was 25 degrees. In retrospect, I could have partially wrapped a portion of the domed lid also.
