Today I smoked some ribs for the fellas tomorrow at work. I'm a fireman. I tried the AMPS for the first time. Had a bit of a snafu. I guess it wasn't fully protected and some fat dripped down into the tray. No good. Fortunately, I still have some chunks so I was able to recover the fumble. I have a MES 30. I'm thinking of just taking the drip pan out of the bottom that way the AMPS will fit under the drip cup and be protected from drippings. The pan at the bottom doesn't look it does much besides being handy to take out and clean. I took it out and fired up the rest of the pellets. Wow. This thing is fantastic. Can't wait to use it to cold smoke. Unfortunately, it's getting warmer here in SoFla so my cold smoking window is closing.
