Planning on doing a vertical offset smoker. Looking for insight on the whole idea, with emphasis on the baffle plate from the firebox to the cook chamber for the best heat distribution. The cook chamber will be 48"X24"X54", bottom rack will be about 11" off the bottom with 6 racks 7" apart. The firebox will be 30"X24"X24" and will have a 8"X23" open into the cook chamber. Planning on making two doors 44" tall by 24" wide. The blue part is my thoughts on making a holding chamber 30"X44". I am thinking that it should get enough heat from being on top of the firebox and when needed the red will be a damper can be opened for a boost of heat. The firebox will be 1/4" plate, the cook chamber 3/16" plate, and the holding chamber 1/8" or 3/16".
Please feel free to offer any insight, good or bad. Thank you
