I'm guessing this is the only one on the lot with the floorplan you want. If so, I'd let them know of your interest in the unit. Maybe talk with the GM if possible. Perhaps provide a "good faith" deposit against having ALL items properly repaired and the opportunity for them to do a thorough inspection by their service department prior to your next pre-sale inspection. Any fails after that and. I'd look elsewhere.
In short, give the dealer to make the unit ready for sale and if they don't they're probably not the right dealer.
Just my personal gripe, but it really boils me that dealers expect the owner to find all the flaws and fails in a new unit, bring it in for documentation, wait for the manufacturer's approval, wait for parts to be delivered and then the work gets scheduled. They are getting almost full MSRP these days. We should be getting an RV that's ready to use, fully inspected and prepared for delivery.
Apologizes for the rant
