Ok, this is just a thought. I wanted to see if anyone has seen anything like this. I've been thinking about making a dual drum smoker sort of like the stacked ones with 2 horizontal 55 gallon drums but have them each operate under the same 30 gallon firebox. I'm guessing i'd need flue's from the firebox to each smoke chamber in order to control temps? I would probably mount this on a trailer but won't even start this project for awhile. Really, I've just been trying to find similar pics online but came up blank.
