The AMNPS works well when inside the smoker, but made it hard to cold smoke cheese (temp variation, overheating). Not entirely the fault of the AMNPS tho, I like to add a few chips to the pellets and apparently they flare a bit, thus the temp variation.
Well, after I melted a bit of cheddar cheese last time, I decided to make the mailbox mod and tried it out yesterday. It worked great with the AMNPS and I got a solid 6 hours of smoke out of it, with additional chips added to the pellets.
Hats off to those that have come up with this mod!
