I am wanting to build a reverse flow vertical smoker. Cant seam to find detailed plans for what I am wanting. It seams like if you used the back wall for both the heat and smoke coming up and the exhaust you could eliminate 2 extra side walls and save on materials. I don't know if that would work or not. never built one and just getting started trying to figure it out. seams like there is a lot of science to everything and really don't know where to start so hoping to find a good set of plans to go by. just want something big enough to do a couple butts on or maybe a whole brisket. Any help is greatly appreciated as my Bradley has bit the dust so ready to go to lump coal and wood burning.
