Just out of curiosity, how's the temperature distribution? Left/right, front/rear, top/bottom? I could go nuts instrumenting that chamber on a test smoke. With the insulated chamber, I would expect a much more even temperature.
Not sure yet. I just did a test with probe in the center of the center rack. I'll do more detailed tests when I finally get the door on. I did the previous test with a piece of insulation taped inside the CC opening. Still A LOT of welding and grinding to do.
