...if anybody has turned over the dump tray to extend the baffel all the way in the main chamber. I will be using the side box
Only had my CG since August but that is the only way I do it. The only problems I had were when I obstructed air flow by putting drip pans supported by foil covered bricks. It seemed to take an extremely long time to cook.
I think the most important mod you can do is get a thermometer down by the grate. I stick a candy thermometer in an existing small hole on the left side of the unit. The built in thermometer never matches that one.
You can make a quick stack extension to the grate by rolling up sheet metal and inserting it into the stack and letting it unroll to support itself. I used some ductwork found at the hardware store for this.
