a guy at work actually talked to me today about using a retired signal cabinet. its a 4' tall 2' wide stainless box that houses the signal computers for the road. Interesting idea. I'll see what it looks like when he brings it to the house.
Since i am laid up at home i am just gonig through a bunch of builds for various ones. I am thinking about encasing the cabinet in wood on the outside to insulate it since the metal is pretty thin. But then i dont need a huge smoker, that is why i sold off my last one. I need a propane one so i can do brisket and not wanting to stay up all night tending to the fire.
