I made this home for my new 22.5 WSM. Originally I was just going to staple a few pieces of plywood to block the wind, but this works much nicer. On my first trial I had no problem holding 225F temp with my stoker w/5cfm fan for 24 hours on 3/4 bag of Rancher charcoal. It wasn't cold, but there was a decent breeze overnight. Even though the box is vented, it was toasty warm inside. I was planning on insulating it, but now I'm having second thoughts.
The best part is that my Stoker would lock up in cold weather, and now that problem is solved.
