Howdy, Davecatmanpowers here, I just completed building my smoker out of a 200 gal. air comp. tank and a 30gal. air tank for the fire box, it's mounted on a small trailer, and has two 35X35 slide out racks, the first outing was okay, mostly consisted of learning what the smoker wanted draft wise, cooked a chicken, beef ribs and corn on the cob and two potatoes, man do I have alot to learn, thanks, David...
