I would suggest you pick the TT YOU like, and that your TV will tow. YOU are the only one you have to please. It really doesn't matter what we think.
Having said that. I would take care about buying a Tt that sits low to the ground. They drag easy.
I would also pay close attention the where the sewer connection is. Seems many builders have taken to putting them UNDER the slide, and you can't reach them when they are under the slide. so IF you need to dump during your stay. You will either need to crawl under the slide, or bring it in. Either is a deal breaker for me.
As for most other stuff. Find a floor plan you like, and make the deal
