As an FYI, I found out earlier this year that my insurance company requires that I let them know if I have anything insured through them stored at an off site location. My boat is stored at an indoor cold storage facility. My insurance company requires the exact location, type of building, security features as well as fire suppression features and a few other questions. They charge me an extra $29.00 per year for the off site coverage.
I'm mentioning this as I am sure that there are many like me that might not realize this notification is required by some insurance companies.
