I'm just getting started building a rotisserie smoker out of a 36" diameter propane tank that's about 48" long. I've been smoking for about 8 years, but never had a cooker this big, so I'm just curious as to how much charcoal (if I don't have ready access to wood...) I might want to start with when cooking with a chamber this size? The firebox will be roughly 1/3 the size of the barrel. I know it'll take some trial and error, I just thought I could get a rough idea. Does twice the size equal twice the fuel, and so on? Any info. would be greatly appreciated.
