Tracker that smoker has never been cleaned except for the firebox. Hey Guys I never bought a Master built because I like to build a fire and use split logs. I always felt that the computerized smokers was cheating. I am not knocking a Master built or bashing anyone who uses one. I just like the satisfaction of doing it old school and using a smoker that is a living and breathing machine. I use a Lyfe Tyme 20in x 48 in pipe smoker with a separate 20 x 20 fire box.
