Moved up to CO back in June and had problems keeping the TBS going using a MES 30 and the AMZNPS at an elevation of 9100 feet. Yes, people really do live at this elevation! Started another thread about that and from the replies it was suggested that the tube smoker might be the fix. Thought I'd do a follow up and say that the tube worked to perfection! I pulled the chip tray and the loader both out like I did with the tray but this time I didn't have to keep re-lighting the pellets. I threw some St Louis style ribs in for the 3-2-1 and ended up getting 4.5 hours of smoke. The ribs came out fantastic but I was a bit worried. My wife was out of town and I had put the rub on them the evening before she was supposed to come home. She ended up coming home later than expected and the ribs stayed in the rub for about three days. I'm glad I vacuum packed them at least. Other than that I smoked them as always. And, now for my very first Qview on this site, providing I can figure out how to load up the pic. I know, pretty basic meal but so dang good!
