We have had CoachNet for many years and they have always given excellent service. Although we rave recently sold our Class A, we have renewed the coverage again to use on our cars. The coverage is far better than our AAA roadside service. It's nice to know that if you are in the middle of nowhere they will send help, assuming you have cell service.
If you have any technical questions on repairing any of the systems on your RV you can talk to one of their tech people for help, done it many times.
