Hello All. I am brand new to this forum, and I am sure this has probably been asked a thousand times, but here goes. I just built a homemade drum smoker and it works well. However it was an enormous amount of work with the liner burnout and all. After I built mine, I discovered Big Poppa Smokers Drum Kit. This would save me tons of time and hassle, (especially when I buy an UNLINED drum this time. Here is my question: The charcoal "nest" from Big Poppa's looks rather small. How long of a cook time can you get from it at say 250 degrees or so? I know mine will go 15 to 18 hours or so, but my basket is larger.
