I'm having a real difficult time keeping my propane smoker over 200 degrees. I had this issue a few months back when it was 30 degrees outside, so I covered it with scrap plywood to keep the wind off and it worked fine for the temp I needed. Tonight with 55 degrees and no wind, still had to board up to get it over 200. I practically closed all my vents.

Seems like in the sun I can get well over 350, but lately it's been a real struggle.
