I shop around and always go with the least expensive coverage I can find. My RV coverage right now is about $350/year for full coverage, agreed value, and $5000 on inside personal items.
I have not made a claim in 30 years and have a clean driving record so I am not planning on using any insurance that I carry so good customer service doesn't mean much to me. Too bad I can't get back the money that I have paid for insurance that I have never used.
My wife was broadsided by a person running a red light who had State Farm insurance and they did a good job of writing the check for her totaled Jaguar.
