My sister worked for State Farm for many years, and I believe some of the info in this thread is completely untrue. And my State Farm agent told me as much when I took out the policy on my Mavic: A personal articles claim will in NO WAY affect your homeowners or auto policies......I believe it's basically against the law. She said if you have some claims on the Mavic, they may ask for a deductible to be implemented to continue the policy, or refuse to carry your Mavic anymore, but it has NOTHING to do with other policies. My sister said if someone's house burns down and there is a claim on the house and all the belongings it defiantly doesn't affect their rates afterword. Insurance can be one of the biggest scams on the planet in my opinion, but they are regulated heavily to protect consumers too.
And my State Farm agent has basically been a family friend for years, so I trust that she would not put me in a spot to 'screw' myself for the $60 a year she is getting from me. She would tell me if I'm putting all the rest of my policies at risk, that I trust.
