I'm doing a brisket on my XL . I checked it before bed 12:30 ish it was at 240. and then at 4:30. 10 hours into the cook. it was at 190. I moved the coals around some and opened up for a few minutes to get flowing again. Now all is good. Most times everything goes fine. Sometimes you have to adjust a little. It's part of the fun of it. I will someday own a stoker. But I'm in no hurry.
