That's pretty cool. Unlike you I place my MES on an old children's card/activity table. With my bad back I can't continually bend down or get on my knees to open the smoker door for whatever needs to be done during a smoke. If I bought the MB Cold Smoker unit I'd have to place it on the ground and then find some kind of flex tubing to connect it to the MES, something I'm not willing to do. That's why I have the AMNPS. I also recently won a A-MAZE-N holiday drawing so now I own a AMNT which is the tube smoker. I can experiment with that too in my MES and in my Weber charcoal kettle grill.
I'll be curious about AMNT, I've been thinking about getting one for my Webbers too! Looking forward to hearing how it goes!
