So I have a duo combo brinkmann grill, one side is propane the other side is charcoal/smoker. I use only the coal side since of course it taste better and now I am hooked on smoking. My dilemma is do I find a offset side firebox and add it to the smoker with all the mods to even out the smoke or convert my propane side to the firebox and make it a reverse flow smoke box with all the mods too. But is that just more work than its worth or to big a firebox? Or should I add the firebox and make the propane side also a smoking chamber so have to seperate smoking chambers? Its a great BBQ so would rather modify to what I want rather than go out and buy a new one. any tips would be great thanks
