My current insurance company is Auto-Owner's Insurance. They only write insurance in 26 different States but they do cover RV's and offer a significant discount.
My personal insurance rating is X868, which is a combination of my driving record, claim history, credit rating, and a few other things that insurance companies use when they determine your rate.
Progressive say that they offer an additional discount if I would combine my auto policy with their homeowner's insurance. The only problem with that is that Progressive will not write homeowner's insurance for my area of Florida.
What I found interesting is that when I went to the different websites to get insurance quotes, as soon as I started entering my information, I found out that ALL of the companies already had the basics, like my address, the vehicle information, driver information, etc. This appears to show that they all share information about their policy holders or your information is available for all insurance companies to see.
Perhaps with the sharing of info, Progressive was just trying to get a policy holder that might not cost them anything in claims. :B
