I was considering a Meadow Creek TS120 this year, but we had some unexpected expenses, so I'm going to hold off until next season. Since I really wanted a new smoker this season, I decided to pull the trigger on a Meadow Creek SQ36. I spoke to the place I'm ordering it from, and they said that they could have the SQ36 welded on to the trailer with the TS120 next year, so (hopefully) next year, I'll have a small grill / smoker combo attached to the trailer with the TS120.
So now I just have to keep myself occupied for the next 4 weeks while I wait for it to arrive. I've got a brisket flat and pot of baked beans in the smoker now, so I guess that's a good way to stay busy. ;)
