Hey all!! I live in a high desert environment. 4k' elevation. I have done a few cooks on my slow n sear, chicken thighs (cold grate method), ribs, and most recently brisket. I have 22.5 performer, use Kingsford blue, and added boiling water to pan, as directed. What I am finding is the coals tend to work pretty hard and burn very quickly, and water pan dissipates in about 2 to 3 hours. I light with Weber starter cubes and approx 12 briquettes. I have talked directly to the owner of ABC BBQ on phone, very good service btw. Anyone have similar issues or have some advise... Thank you in advance!!
