In our almost 30 years of RVing, we've had only one road service, CoachNet, so I can't speak for the others. But here is an example of their value to us.
One Sunday after Thanksgiving, we were returning home from Huntington Beach State Park, in Murrellls Inlet, SC, when our right front brake locked up, as we approached Conway, SC. This was around 7 PM. I pulled into a K-Mart parking lot and called CoachNet. Their first question was "Are you in a safe location?" I responded that we were in a K-Mart parking lot in Conway and gave the street names.
After describing the problem, the person I was talking to said let me check and I will call you back in ten minutes. In less than that amount of time she called back with the following information. "You have a warranty issue, so we need to get you to a Workhorse (the manufacturer of our RV's chassis, service facility. The closest one is more than 100 miles away and, of course, closed." We agreed that our best option was for Sarah to take the dogs home in our toad and I would spend the night in the parking lot.
She said, "I will call the K-Mart to tell them what the issue is, but please go in and talk to them, yourself. I will call the Conway police department and tell them about the issue. We will call you in the morning and tell you what the arrangements are. How early will you be up?"
The next morning, I was called around 7:30 and told that a tow truck would be at my location at 8 and that the coach would be towed to Whiteville, NC, about 44 miles away. The tow truck showed up at 8:05 and at 8:10 I received a call from CoancNet asking if the tow truck had arrived.
We would not travel without CoachNet.
