WE had Progressive for 10 years and the premiums went up every year. I assumed it was because we had moved up to more expensive coaches. We're had the last coach five years and the premiums went up 50% with the only claim being $70 to fix a windshield chip. When I received this years notice, it was up another 40% due, they said, to my wife having a chargable accident. Ten days and lots of faxes and phone calls later, they agreed their data was incorrect and lowerd the premium to ONLY a 20% increase over the previous year. I went with Forrmost, a Farmers company. Premium was 40% lower than Progressive's "adjusted" rate, higher coverage and included road service and towing.
