I second the sea salt in the air. Need to wash it down ASAP after leaving the beach along with any other metal items that were outside and exposed. If you are at a site with water hookups spray the camper down a few hours before leaving and allowing time for it to dry.

If it was windy and sand blowing. I wipe my hitch ball, coupler and WDH sockets clean and apply new grease when leaving.

Don't forget the AC unit, salt eats the fins very quickly.
