I got a chargriller competition pro and am waiting on the rest of my materials to finish my desired mods but I extended the chimney down to just above the grill and seasoned it today. Since it was hot after a few hours of just seasoning I decided to toss on a pork butt.
First cook did not turn out perfect but was still good. The rest of my mods will make a big difference in stabilizing heat. I live on an island so never have to worry about cold weather and can smoke all year. Should improve pretty fast.
