I ran across these tanks at one of my customers. They were going to scrap them out, so I got them free. I know most of the builds i have seen on the forum people are looking to build a bigger smoker. I am looking to build something a little smaller. I already have a large trailer smoker and fire it up often to do a couple of butts or 2 or 3 slabs of ribs for the family. I will still use it for my catering and large events but want a stationary smoker for the house. This has been on my list for a long time but I am going to get it done this winter. The original plan was not reverse flow but after seeing BBQ Engineers build, I am changing the design. Once the plans are complete I will post for suggestions and comments.
