This smoker was given to me and I am in the process of turning this into a RF but I do not like the size of the doors that are currently on it right now they are way too small. I thought about just welding them up and cuttting on the other side but someone has allready done that once before. I feel like I am at a crossroad right now. I can pick up a new "used" tank this size for around $150 and start over and maybe transfer the firebox over to the new tank. I dont want to get too far into this just to realize I cannot make the doors the size I want them. I figured I would tap into the weath of knowledge on this site for help. Here is a shot of the back. You can see where the first door was.
