We Use Progressive for RV insurance
... and unfortunately we had a claim the very first week, when a storm wrecked our awning and we were still novices. An $1100 claim. Progressive was great and paid the claim quickly, only asking to see the trailer and take pics, since the policy was brand new (and he implied that otherwise he would not have to come out). He had a printer in his car and printed me a check on the spot.
They also offer replacement coverage. The policy for our $19000 2005 FR Wildwood runs about $570 per year. I'm happy with them, so you should compare their rates and coverage with GEICO.
By the way, I had to sue GEICO once when someone without insurance hit me and I was injured. GEICO stalled and stalled and stalled on paying valid medical claims until I had to hire a PI attorney, which should have been unnecessary. In my opinion, GEICO is great UNTIL you get hit by another driver with no insurance and there is no way for them to subrogate (pass along the costs) to another insurance company. When that happens they cast you into the Insurance Purgatory department.
Get the facts, not the gecko hype. Check out the GEICO complaints. They are not anecdotal, and it cost me an extra 35% in legal fees to find this out the hard way.
