It certainly sounds like a an especially awful purchased-new-boat experience that shows poor quality control on that boat at least and essentially zero customer service afforded to you the buyer. And I do greatly sympathize with your RT travails.
But could you clarify a few things? Did you end up buying from one of the FL dealers who was dropping or otherwise losing the RT line of boats, or did you end up buying from the one 3 hrs away?
It's a shame, after apparently buying the 2017 model RT29 in Nov '16 and experiencing so many problems in response to which the dealer remained passive or worse, you neglected to contact the manufacturer in WA long before they saw your post in Tugnuts on April 2017 and responded to you with offers to make it right. You participated in a Tugnuts forum thread before you actually made the purchase, I believe, in which other posters advised contacting the factory/parent company if dealer customer service was found lacking , as yours surely was according to your painful report.

Have the RT factory folks actively been working to make right all your listed issues since 4/7 , ...or was that all public-forum promises then that have not been followed through with in the month + since then and that is why you post this negative report now?
...If... the factory just heard about your issues in April, and have been helpfully active on your behalf since then , it would seem like a bit of bad timing to just now give a very negative review of RT in general, rather than of the poor dealer I don't think you have yet named ( & why not?).
It would be interesting to know whether the factory was ever informed even by the dealer of any of your RT 29's issues during the 5 months until they 1st reached out to you .
I sure hope they get you and the 29 squared away( or replace it for you!) for a MUCH better experience going forward, and they find someone else besides (in place of) your selling dealer to represent them near your FL location.
Best luck.
