Fine print says "not responsible for theft or damage." I lost my whole camper. Police say it's probably in the back of someone's property, being used for a hunting lodge. Good thing for insurance, but we're remembering things we didn't claim three years later.
Just like at home: make a list, or better yet, video your possessions. One person shoots video, the other pulls out drawers, opens cabinets, etc. I keep the video of the trailer at the stick house, and the video of the house in the trailer..
