New to her, but needs some repairs... Dealer obligations?

You did not specifically say she "signed" a purchase order for it, so I have to hope she gave them a list of what she noticed was wrong with it and then tell them to go over the trailer and fix these specific items, get a list of everything they else they inspected and the results of thereof and THEN re-negotiate the deal and get some sort of warranty from them on it as after all it is a 2014 model. If she already signed to buy it, she is screwed.
