Hi All! Newbie here! I just got my 1st smoker..It's a Perfect Flame Vertical smoker. I'm in the middle of planning out a full day of smoking ribs, chicken, etc...and was wondering how many hours I can expect to get out of a typical BBQ propane tank? Also, if anyone has had any experience with the Perfect Flame Vertical smoker.....looking for tips, suggestions, or things to expect. Any response would be greatly appreciated! Thanks!
