Here is my ad for CoachNet: I have had CoachNet for a lot of years and been very happy with them. It costs $250 the first year for a motorhome, and $180 per year for the next years. Considering that a tow with a "monster" truck that took me only a mile cost $500, that is an excellent deal. They will tow you to whatever is the nearest facility that can repair your vehicle. And they do NOT take you somewhere unless they check with the facility, and it can start work on your vehicle right away--no dumping you in the back part of the parking lot. That is extremely valuable if you are on vacation and don't want to hang around for weeks waiting for a fix.
Also, if you have a problem and your vehicle is still driveable, they will help you find a place that can and will work on your vehicle. For example, a month or so ago, I drove down from Lake Louise with a badly missing engine that had a check engine light on and occasionally blinking when I drove up a mountain. I got parked at a campground and had called several truck repair places in the area around Coeur d'Alene, ID, and no one could or would work on it. (They only work on diesels and mine was a gasser. The door to their shop was too narrow, the door to the shop was too short, their service people don't know how to work on motorhome motors, they don't have a lift, their insurance does not let them work on motorhomes, etc. etc. )
I called CoachNet and within a couple of hours, they had found a "speed" shop in an industrial park nearby that worked on hotrods, but also had a lift big enough for my Class C!! They could take a look at it the next day (a Friday) and diagnose the problem, but probably could not do the repair until the next week after they got parts. I took it in, and they found a bad cylinder, but one of the service guys was suddenly available because he was waiting for parts on his job, so he started work on mine and replaced a coil within 3 hours and charged a reasonable price.
They also will offer technical advice over the phone and try to diagnose the problem if it might be something you can do yourself. One time, I was in Frisco, CO, and no Ford or other dealer would fix my radiator hose that had dumped all my coolant. I was in a campground, but they sent a mobile mechanic the next day who found a loose connection and added fluid! They paid for the mechanic to come, and I paid for his time to fix the hose.
Those more-than-just-a-tow things have been worth every penny I pay for CoachNet. They also are excellent about calling me after things are fixed and getting my feedback!!!
