From what I've noticed here theres a ton of experience with not only building but designing and cooking with smokers. I would rather read as much as possible from others on their individual experiences before I start any new build, not in too big of a hurry as it's currently too cold to stand in my shop for very long. I have 2 options for a smoker build and I'm looking for opinions. Option 1 is an old propane tank that measures 15" in diameter and 46" long, I also have an old air bubble 13" dia and 22" long that could be used as a fire box, I'm not sure of the wall thickness but it is somewhat heavy. Option 2 is a diesel tank formally used as a day tank for a local Hospital back up generator, its dimensions are 43" tall, 24" deep and 25" wide. I'm not looking to cook for 100's of people just a few so I was thinking of something fairly small and efficient. Horizontal, vertical, reverse, offset? Thanks
