Welcome Rocky mnt camper (& Mrs camper),
We don't have a Passport so I can't offer first-hand advice on the trailer, but in reference to damage on diamond plate -- it's a brand new trailer, and I would
want any damage fixed/replaced also! Any repairs made by the dealer should be documented (in your dealer/sales file) & recorded with the manufacturer too.
Photos #7 & #12 in this ad, show a thermostat (on the wall behind the booth, just left of the refrig)
