I see the concern regarding opening the doors (to add more wood?) and agree that you would lose smoke and heat. Not mentioned is that with the
AMNPS you load once for the entire smoke. That eliminates the need to repeatedly open the doors. Owners of the MES Gen 1 have implied this in other posts. Also not mentioned, if you have the funds, are smokers from Smokin-it and SmokinTex that require just a chunk or two of wood for an entire smoke with no need to open the door until the food is done.
I would guess the
AMNPS would work in the Cajun smoker, but to be truthful, I just do not know.
