I had one on a motorhome we used to own. Everything was fine with the first claim for steps repair. The next one was for a shot microwave. To get it repaired I had to pay for removal, pay freight costs to ship it to someplace across the country for evaluation and possible repair, then pay for shipping it back. In the fine print it said shipping costs for parts were not covered. I pulled the old one and bought and installed a new one myself. Never again.
I have had Coach-Net and used it once. Very good service. I have the Good Sam service now but have not needed it.
