I started with Coach Net since I live about 5 miles from their home office. When I needed them, I was already in American Heritage RV park in Williamsburg, VA. They couldn't find the CG. And you hardly ever see an RV at Colonial Williamsburg, except for the hundreds in their parking lots.
I switched to AAA. Had a flat on my car on the expressway in Cincinnati, where I live. Several hours and many calls later, he finally showed up. Claimed he couldn't find me until I told him to drive down to the foot of Walnut street and look down, and I'd wave to him. I now have Good Sam. So far, their service has been perfect. I haven't needed to call them, yet. Let's say that I'm guardedly optimistic.
