You mean the original equipment cover? Or something to insulate the smoker in cold weather?
The OEM cover is NOT waterproof without spraying it, and the spray breaks down fairly quickly. I quit using mine and switched to a cheap tarp and a couple of long bungies for storms.
You can insulate it with a cheap welder's blanket and a 3-4 spring clamps.
LOL that's funny!I live in Vt. and I haven't seen a need for one either. I've smoked in the single digits before. Normally it's me that gives up instead of the WSM.
