Thanks Second Chance. I did talk to my State Farm agent. If no homeowners or renter policy, then no content insurance possible. Dad was in Merchant Marines not US Navy, so that's a no go I think. The USAA website says for military families.
I've done some searching but not finding much regarding policies to protect your stored stuff while full timing. Most policies require you own or rent property to cover. I've been with State Farm for 30+ years but they won't insure personal items in a storage unit if your full timing. I'm surprised this isn't a much discussed issue. When I called and talked with two different Escapee CS they indicated first time anyone has asked about it. Any pointers to reliable insurance that is not limited to less than 25K would be appreciated!
