I've used progressive for quite a few years, on two different RV's. Very happy with them. First TT, was caught in hailstorm. they ended up totaling it because replacing the aluminum siding was going to cost more than it was worth. They wrote a check to the bank, paying off my outstanding loan, I bought it back from them for 2K, owning it free and clear. On my new cardinal, I was with my insurer for my car/home, but was going to be $1200/year for coverage. Changed back to progressive, $460/year. If you are full timer, they may not be that cheap, as one of the questions is "how many days a year will you use the unit". If you answer honestly, it does change the cost.
