I asked your same question on this site when we were buying and had the most positive responses about Progressive and that is what we went with. I have only heard good things about the claims experience. Make sure the insurance company knows you are talking about an RV - as the vin# often comes up as just a van. i liked that when I talked to Progressive they knew exactly what they needed to have in place for an RV in the policy which was not my experience when I spoke with the company that has my car insurance (which is one of the big companies - and I have been with them for 40 years). Plus the rate from Progressive was a lot less for better coverage.
