Hello all, Looking at building a new smoker to camp with. Most of our camping is done with a altitude over 6,500 feet. Has anyone had any issues smoking at this altitude or higher? He have camped at over 8,000 feet the summer before last. Okay should I build it with 3 or 4 1 inch air intakes? I picked up a Craig list Weber for the top and it is just a bit to small for the drum. Any recommendations on how to fix this? Thank you for your help.
