You don't mention what RV you have. If it's a small trailer towed by a pickup, that's one thing. If you have a 45 foot motorhome, that's a whole different animal. Coach Net has technicians on call 24/7 who can assist you in troubleshooting, even when it's not something you need to be towed for, whether it's the generator won't start or the sewer drain is plugged up, or...
CN also understands that a large rig needs a different towing arrangement than a car, they'll find someone to do the towing/service, and they'll follow up until you're done. I recently had a valve stem extension unscrew (my fault, as it happens) from an inner dual, and I was unable to get it back in -- couldn't find the stem on the wheel -- so I called Coach Net. They called a service tech over an hour away (I was near Yellowstone, in Gardiner), and paid for the service charge/mileage -- it just cost me ? hour of his time. The previous time I had to call them, after their tech suggested a number of things to try/check out, they then sent a tech to work on it (didn't need towing, generator problem), but he was much closer (at QZ).
Regular insurance would have left me with a lot more hassle, and more cost. Plus, should I have to be towed, it's more than just "to the nearest shop." And they follow up. It's worth it to me.
