The best is to return it to the service center. You just can't tell what you are going to get from the Dealer.
We bought a new 5th wheel in 2014 and showed up a day early. It was a mess, and there were 30 pages of inspection notes the Dealer generated - some get billed to the transport, some back to the factory (if approved). We were not supposed to see that list, but I copied all of it with my phone. You wouldn't believe what didn't get fixed, apparently because the "factory" didn't approve it. All lip service to me - I just made them fix it all, plus some I found on my own before we took delivery. Even then, we had a year worth of issues before it settled down to be a nice rig.
I know 5th wheels are different critters compared to motorhomes - kind of
