Congratulations on your new "condo on wheels". Like Don and Monica said, walk thru, switch every switch, pull every shade, open every draw and open every cabinet. Our new Landmark came in last week and we have been to the dealership already with pencil, paper, post-it notes and scotch tape. I have stuck notes numbering them and written down every finding both for the manager's list and a copy for me of findings so far. I numbered each note to the master list so there's not any questions about where or what this note is about. The dealership is pulling the camper into the PDI area next week to address every finding, hopefully ready for us to take home the end of next week. It's a very good idea to stay at the dealership overnight to investigate the coach without being pressured by a staff member.
Good luck and happy traveling.
