So I am in the design process of my next cooker. I have my fridge conversion that can hold roughly 25 butts but with my catering gigs I have lined up for this fall that wont be enough space. I am wanting to build a heavy insulated G2 Competitor that is very efficient and to also you at competitions. I would use the clone for big meats and my fridge for ribs. I was just going to build it to almost exact dimensions but having hard time finding certain dimensions and design features. Anyone able to help me with the below questions? 1. does cook chamber size on site include water pan/ 2. firebox size? 3. does the frame make the corners really hot? 4. distance between false wall and insulated wall, is there a false wall on both sides and back?
