So, I got a 275 gallon oil tank all prepped and ready to go. I put three doors on it. Two horizontal doors and one big vertical door. I'm getting some flat stock to put on around the doors to help seal it. I'm debating on where to put the fire box. Part of me wants to do the traditional side mount box, but a HUGE part of me says to mount it off the back. After researching store bought smokers I started watching videos on "The Good One"s website ( http://thegood-one.com/ ). I am intrigued on how they used the shape of the smoke chamber to force the smoke to circulate in the chamber itself. I was thinking that a rear mounted firebox could utilize the shape of the tank to do the exact same thing. I was thinking about either flush mounting the stack dampers on the existing holes (kind of like they do on their smokers) or dropping a pipe down into the chamber itself 6"-10" Thoughts?
