No, to answer you question, but: Jayco had a regional rep in our area (don't remember his name or title) that could tell you when a specific Jayco PUP, TT, or MH would be built. I think the dealers can access the info you're looking for through the regional reps. My guess is that your TT has already been assigned a slot in the next scheduled run of that model. And if you make the right contact at Jayco they will tell you when that is. I would want to watch mine being built.
We ended not ordering because we went with a different model off the lot, but our regional rep could tell us when it would have been built. I don't know about delivery times.
Edit: It was about the same time frame as djalbrec's.
