The best mod that I have done on my Brinkman was to make a deflector plate that fastened in the chamber on a 60 degree angle down to stop the coals from grilling the meat closest to the fire box, and even out the smoke throughout the chamber. I made it from 1/16th inch metal, and used the screws holding the firebox to the chamber to also hold the deflection plate. I also raised the bottom grate in the firebox to allow more room for ashes, and increased air flow. I rolled up aluminum sheeting to lower the exhaust closer to the grate for more uniform temperature. Needless to say, I have turned out some fine meats with my set up. The main thing though, is gaining consistency in the cooks; doing the same thing every time. That means cooking a lot, which we all enjoy. Good luck cooking. May the smoke be with you. :clap::-D
