So here is the smoker I built 3 years ago. I was fed up with my "BBQ Grill" that i added a fire box to, and decided to build this to handle any weather conditions. It is 2" square tube, 14 ga steel, insulated, 5 racks, can fit 10 full rib racks, 2' X 2'and stands 4 1/2' tall on casters. Ive been using it with no problems, and very happy with the end result.
