That isn't being disputed. I'm just helping to make the information for the roster is accurate. That being said, so far, 2688 is the lowest number 2016 model I've seen (and driven). I'll check more registrations and builders plates to find out where the 2016s started.
Just a quick FYI - there are no 6000s in service at Yukon. Last one was towed off property last week. I believe it was 6293. There are only a handful left at Castleton.
8184 has been in for a while. They've also gotten a bunch more Novas in. When I went there yesterday, the highest I saw was 8223. I'll update once I return next week.
Yes, both of those buses are in at Castleton.
On a side note, all 2713 and 2725 are no longer in service. No DL3s remain in passenger service at Castleton.
