My UDS has a pretty large charcoal basket (15 inches in diameter). I place wood chunks throughout the basket on multiple levels and use minion method, however, it only produces smoke for the first hour. My wife is asking for a Christmas list and I'm thinking an AMNPS is the way to go (probably the tube because I want to use it to hot smoke 225-300). I see people building mailboxes to attached to their UDS or modding their UDS to allow for more airflow for the AMNPS. Will the AMNPS not work in a standard UDS with a BBQ Guru?
