I switched to Coachnet last year, and unfortunately had two opportunities to use them. I was very happy with their service. The first time they provided a tow on a Sunday to a service facility that could work on my coach the following day. The second time they sent a mechanic to help me move a stuck slide.
The tow bill I didn't have to pay would have been enough to cover the service for a number of years.
The only complaint I had with them, and it wasn't their fault, is that the phone number they gave me was incorrect. It was the line WRV had set up for that service before they closed their doors. They have since replaced the cards with one with a different phone number.
For the price, ~$100/yr, you can't beat it for peace of mind.
