i just recently started building this a few months ago and this is what i have so far with the little time i have and acquiring material from work as i come across it. the grill is 100% stainless steel. i used the double barrel smoker idea. i have used the grill twice now and have yet to smoke something as you can see the smoke box isnt quit done yet. i am going to ad stainless paneling to the bottom to hide everything and put a door on the smoke box. i would greatly appreciate your opinions and comments on the grill, as i am new to smoking and am open for ideas. you can view pics at www.tdenterprises.net/smoker.htm
