Coachnet fan here too. Fees went up about a year ago but I will stick with them. Have used them three times with the RV, once in Alaska for a 350 mile flatbed tow in '08. All three times were quick responses (as possible) and professionally done. No added costs to me - I simply signed and was done. They deliver what they promise. I figure the Alaska tow alone give me another 12 years or so of "free" service before I am behind what I will have paid out.
Do read the information carefully so you are clear about what you get with ANY roadside assistance program. One thing I LOVE is Coachnet's tech assistance via phone. They will help troubleshoot and decide if it is driveable. They will call ahead to get you a service appointment for a repair using their network of approved providers, sending a tow truck if required. (You will be responsible for the repair costs.) Have had to use that service four times over 11 years. A relief to get sent to a qualified shop easily.
Much as I love their service, I hope to only recommend them -NOT use them!
