The MailBox Mod Rocks! I finally did the mailbox mod on my MES 30 Gen1. I have had the old girl for years and it is a really great little smoker. But darn near every time the smoker would get over 230 my AMZNPS would catch fire, this is the fix for that! I also recently bought an Auber PID which has greatly improved the temperature fluctuations. Got a mailbox off eBay for $16 bucks. Built some legs from some old car trim. I already had a 3” flex hose and high temp silicone. Had these old 3 ½” turndowns from a hotrod exhaust project that I never used. When testing I put probes near each of the 4 walls and used the iGrill to monitor temps, not too bad. TBS - She is really cruising along now!
