I see what you are saying, but the draw from the stack pulls the heat into the CC, so it would be hard to keep that even between the two. I would since your talking smaller cookers, put 2 back to back on the same trailer. This way they would work trouble free at what ever temp you choose.

Current Smokers: Backyard RF Offset and Hybrid RF Offset trailer rig with Cowboy cooker and fish fryer, always room for more........
I was thinking about the same idea when I was planning the smoker I'm building now. I've seen a couple built that way. One guy i talked to that has one wished he would have just built 1 bigger one. He said its hard to keep the airflow right in both of them at the same time. I decided to just build a big one (maybe too big) to try to keep it simpler on me. I'm not saying your idea wont work because honestly I don't know. I'm just letting you know why i ditched the idea.
You could decide the fire box too. Then two air intakes and two stacks would resolve the air flow problem. Effectively becoming two smokers stacked back to back
I hadn't thought of the draft part of it, then again that's why I asked before I embarked on something new again. I had thought of doing dual doors on the firebox, so then a 1/4" divider would be easy enough to add in. I have a GOOD bit of 3/8" plate that I got, and keep thinking it would make a NICE large firebox. I have somebody with some 3/16" plate for free, just have to go pick it up, and still have some 1/4" left over from my build. Pick up some angle, extruded, and a few other odds, and ends, and I'd be set after I find a tank. I also found a 250 gallon propane tank I've been eyeing I may go get and just do one good sized smoker.
I like the K.I.S.S. principle. I was going to make my larger trailer build with two potential cooking styles (vertical center feed and offset RF). Decided to keep it simple and nixed the center feed. I can always build a center feed next time right..
Well, got my next victim today. Picked up a 250 gallon propane tank for $80. Some minor surface rust, but no pitting anywhere. Still had a little bit of propane in it, so no moisture got inside of it either. Now to decide on which way to go with the design aspect. Definately going to go with a main cook chamber with a squared off door setup, and a warming cabinet over the firebox that can double as a cooker at a different temp. Also found ALOT of 1/4" plate, but it's rusty. For free though, I can grind the rust off to clean it up and use it.
Here's my rig if I ever get back to work on it.
I have a shut off to the main chamber and a slide in divider for the firebox if needed. Both warming chambers can be used to smoke or warm if shut off.
I like this setup because I can just smoke on one small warmer if I'm at home and cooking dinner for the family.
I have a simliar idea. I plan on building a square warming cabinet over it, and building a channel into the WC from below the BP, and another above it. Then if I close off the main cooker chimney, the heat will have nowhere to go except back up into the WC when the lower cutoff is opened. But if I wanted to I could use the smoke and heat after it has passed through the main cooker, and divert some back to the WC to use as a low temp smoker. This idea also would go even furthur to preventing any chances of flame ups happening in the WC directly over the FB. I need to work on a drawing for what I have in mind and post it up. In theory I think it will work, but want to run it by others before I start cutting.
