I got CoachNet in 2005 when I got my motorhome and have kept it up every year since then. I've had three occasions to need their services (broken hydraulic line, seized brake caliper, tire needing changing). The first two calls required tows while the tire just needed a guy with a jack (it was on my car).
In all three cases, Coachnet gave me excellent service. I was able to rapidly speak with an RV Technician who asked clarifying questions and could have offered suggestions if there was anything I could do. When it was decided that I needed towing, they arranged for a huge tow truck to disconnect my driveshaft and tow us to an authorized facility - both tows were about 50 - 100 miles. They also contacted the facility so they knew we were coming. They also followed up in 2 hrs to see if all was resolved.
Coach Net has worked out very well for me since 2005.
