Good afternoon SMF! Name is Dustin. I've been reading the posts for a while trying to learn all I can. Thank you all for the amount of effort you put in here. I'm in the planning stages of building my first smoker. I'm working on the dimensions for the fire box. Can it be too big? My cooking chamber (CC), 16" diameter 25" long, is small because I don't want to use a lot of wood. And I only want to cook one brisket and chicken at a time. But I want to have a large fire box because we have two other smokers with large boxes. I don't want multiple stacks of wood for different sizes. So what would happen if my fire box is too large?
