Buying a Former Rental Class C. How many of us out there?

Hi
I ordered a 28a2017 through the Manassas va. Location . Anyone have any information about getting an inspection in that area . They say they are refurbished in Mesa Az. And then driven to va. Via .hired driver or 1 way rental. Has anyone purchased extended warranty and attempted to use it . Should I expect or ask for anew set of tires . Should batteries be new ? Do they do a complete trans mission fluid change with a new screen.
