I am thinking of replacing my fire box with a new insulated version. I guess I am one of those guys who always likes to improve or modify things. My smoker works and cooks great, so why mess with it ? I was thinking I could make it more fuel and cook efficient. My smoker is an RF. Here is what I was thinking. inner box 20" x 20" x 20" 1/4 " plate Outer box 22" x 22" x 22" with 3/16" top, bottom and sides 1/4" in back and front. About an 18" x 18" cut out for door in front. Door out of 3/8" and use 2" insulation in between
Not positive, just kicking it around. We are going to start on a new smoker pretty soon, may just incorporate the firebox idea into the new smoker.
Anyone else made this type mod? if so please give me feed back
