Water Leak, AC Leaking, and Bunk Breaking: Brand New

None of us can provide those answers without more information. Depending upon the severity of the leak and the duration of the leak your camper could be dried out and fixed or it could be ruined.

10 days from delivery you should be covered under warranty, unless they are able to show that you did some damage to the camper in those 10 days.

What make/model camper do you have? I'm confused how AC condensation leaked inside onto a mattress, unless its maybe a popup with a window style AC unit.
