Neil is right...
If he is offering aftermarket warrenty, he is basically "Certifing" it for the warrenty company. So any items covered by that warrenty "Must" operate acording to that agreement.
And again, what is cosmetic, and what is not has a lot of latitude. When we bought our UA, the dealer was awesome about any problem we brought up. The trick really is catching the problems during the PDI. Take your TIME, don't be in a rush, or let them rush you. Make sure you drive it.
Our dealer in SC, arraged camping sites, we arrived the night before. Saw the coach briefly, and inspected it "without" them around. We slept on it, then did the PDI in the morning, after we were satisfied, we signed paperwork, then started our "Move". While we were moving, some things were handled then.
If we didn't have so far to drive (Back to WI) I would have wanted another day.
Another thought that I wouldn't do again, is having it delivered on a weekend. Not only was the dealership superbusy, they were "weekend" staff. I think you get much better service during the work week.
Congrats and goodluck!
