Ok have the older smokey mountain smoker am tired of having to add chip or chunks and don't like the fact they don't burn to ash. So after looking around on here did the mailbox mod but since made a different box all together. Bought an amnps 5x8 and tried it out mainly wanted it for long hot smokes not much into cold smoking yet. Anyhow after having trouble emailed back and forth to todd didn't realize most the mailbox mod smokers were elec. Ended up getting a 12" tube smoker and tried different spots in smoker and either caught fire or smoke was on the lite side. So tried the tube in the box and if I put a computer fan over my vent hole catches fire and no fan little smoke and also think the flame is affecting some of it. Looking for ideas. Might sell the smoker and get the masterbuilt xl.
