Been smoking for a while now and did pretty good with my modded master built propane cabinet, I have 9 new stainless steel food drums I just got for cheap, thinking of building a double stove style with a third drum off the back being down flow and colder so I could do fish and a brisket at the same time, was looking at a Qmaster draft controller to go with it, any thoughts or down falls you might see going this route
