Ok before the smoker goes over the hill!! How much charcoal do you use on an overnight smoke of brisket. I threw a 12lb packer in a 10 last night and now at 1PM it is just about done. I used a 20lb bag of kingsford and a 12 lb bag of Stubbs lump I found at Lowes. 30lbs of charcoal just seems like a lot. This is my 4th or 5th brisket and I don't ever remember using that much. Winds overnight and high humidity and I had to run it wide open to maintain 200 to 225. It is an offset vertical smoker. Now I am batteling ash buildup restricting air flow. I will probably be doing some mods in the near future Not the best picture but only one I have right now on this computer.
