As has been said, see if you can cancel this sale.
You need to slow down and take a break from your recent experiences.
You said that you wanted a new TT because of your feelings about the stolen and recovered TT.
But now you've acquired a new TT that you are unhappy with for at least a couple of reasons.
There is no hurry to get a new TT unless you have an immediate trip planned that cannot be cancelled, even then you could rent something for an immediate trip.
You should take your time and look at a lot of TTs, ask a lot of questions. RV shows generally happen in January through March. Try to get to at least a few shows and look at lots of models.
There is a lot of experience and expertise here on the forum, but you should be asking questions of the forum members BEFORE you buy. Then you can use that knowledge to help you decide on what is best for your needs. Posting your disappointments AFTER you've bought will get responses of sympathy, but that isn't going to help your situation.
You should be thrilled when you take delivery of a new TT, you should not be having buyer's remorse just one day after you've purchased a new TT. Good luck with whatever you can do at this point.
