Just wanted to post a few pictures of my MES 30 mailbox mod, which worked out GREAT! I've smoked a couple of times now with this configuration and it's a billion times better. Before I had the AMNPS on the rack next to the heating element, and it would cause the pellets to flare up and cause my temps to fluctuate. Now that the AMNPS is separated, my temps are rock solid all day long. Also the AMNPS finally burns at the consitent rate it is advertised to do!! They used to burn up within a few hours, now I got 6 hours out of about 2 rows (it was windy that day).
Pretty simple set up, got a couple of those variable 3" elbows, hooked them together with the right bends, cut a hole in the mailbox with metal snips, cut tabs on the end that gets inserted into the mailbox and folded half of them back so it secures it in place, then use foil tape to seal everything up. Some leftover 'shelf grade' plywood and 4 locking swivel casters for the base.
I plan on purchasing some small metal L brackets and attaching them to the wood base so that things don't shift around.
