I started out with Blue Sky (referral from dealer) and compared it from an offer thru my own agent at Farm Bureau, where I have everything else. He said that the coverage was comparable, but for the extra 50$ a year, he would go with the BS policy, as it had great coverage for guests, that might get injured in or around our 5th wheel. So, we went with BS. No claims in the first year. But wait, the second year premium went up 50%! Needless to say, we're now with Farm Bureau for everything, except the motorcycles, as Progressive had better coverage less expensive.
Good luck with whoever you choose!
