Okay, really I love the Big Boy threads, and my wife just texted me that mine showed up at home, but I'm stuck at work until 5 and have an hour drive home. So over the long holiday weekend I got ready for it to get here, and played with my reefers, breaking them in. Since it was out already, I first took them around with my MTH RK Cab Forward.
Then a couple days later I got the O72 track out and my K-Line BB and pulled them around. I still used the SP caboose as I don't have a UP one yet. I was saddened as the KL BB wasn't smoking, not that it ever did that well to begin with. So off the shell came and I found that not only was there a super tiny intake hole for the fan, but that the gasket had also swollen so that the fan couldn't spin. So I preformed the TMCC smoke unit mod and now it smokes wonderfully. But the video is before I did the mod.
EDIT: Got the videos fixed.
