Well I'm smoking today with my MES 40 and I'm on the cusp of building my first UDS. Just sitting here thinking, has anyone ever made a side fire box for this thing? I know we have the smoke daddy and the AMAZEN smoker but I'm thinking about building a large fire box and plumb it to the chip tray opening. This would be for the heat and the smoke, use it instead of electric. It might be a dumb idea because it just works so well with electric but I want to test with the flavor of charcoal. Just wondering if anyone has ever tried this?
