I have progressive insurance on everything that I own and have insured. A car a truck a boat and 2 homes. The have been great to work with. I will say that I have never had a claim with them. Price and customer service is what sold me on them. I know several anglers that have progressive on their boats that have had claims and they tell me of nothing but good things as well. One guy took off his lower unit while pre-fishing for a tournament and within 48 hours he had a new lower unit delivered to the hotel and he replaced it himself. That to me is service.
If my trailer broke in half, I would have called the trailer manufacture not my insurance company. Trailers should not break in half.
