Thanks to all those that have offered advice. I have no idea where I am going to find the TT I want along my way. It most likely will be a dealer, but also might be a private party if they have what I want (In which case I will try to quick sale the Jayco). I will be looking all along the way in every city and rv park I stay in.
I called in late Friday and talked with my local county tax assessors office where you register cars and TTs here in Texas. They did not know the answer. I will go down on Monday in person to ask again. I think the only solution is if they offer some sort of Quick Title or a Expedited title service I can pay extra for. Something like the passport office offers.
