What a bummer that is !
They don't make them like they used to.
I remember when we bought our first TT twelve years ago.
It was a Pioneer 19T and at the time, everyone here on the RV Net used to say it was a low end trailer.
My wife and I could never figure that out, since we never had a problem with it.
Then we wanted one a little longer with a sofa in it, so with out trying any others we searched all over the country for another Pioneer, and found one of the last ones made before they went out of business.
That one is just as good as the old one the only problem which was fixed free was a cracked Thedford toilet valve. (the dealer evidently didn't winterize it)
I hope you get your new TT straightened out and you have many happy years with it
