Ok well I am looking to build my first smoke house. So far I am looking for a 5'6" tall and built to fit oven grates that I will use for my grates. Planning on plywood interior with aluminum lining. Also planning on insulating the smokehouse with either pallet wood, or barn wood stained exterior. The smoke house will be a temporary set up as we just moved back to MI and have yet to find our permanent home yet. So I am planning on building it to come with me! (Maybe) Here comes my question. I would like to do charcoal and wood, not electric, or propane. How could I build the box to be able to take the heat so to speak. Later when it becomes a permanent place there will be an exterior firebox piped in. Just wondering if you guys have any ideas on how to make this work out.
