I really don't think dealers inspect a whole lot especially if the unit is new. I was looking at a new unit on a dealer lot during a rainy day. Entered into the unit and heard dripping in the shower. Opened the door and the skylight was leaking bad. The salesman looked at it and said, "guess I need to get that checked out". This too had been on the lot through quite a few rainy days and either nobody noticed or they didn't care. I too would now demand a leak test and report as a condition of a sale.
