Whoever you get, ensure that they cover RV's, and RV Contents. Most 'add onto car policy' companies often do not cover many things, including contents......which is why they are much cheaper.
I liked Progressive's ability to choose, the disappearing deductible that starts very high to lower premiums, and the 5 year replacement at then-MSRP price.
But.......realize this. The exact policy in one state is very different than another. You can't ask a guy in Maine or California for cost advice if you live in Nebraska (e.g.).
