Beware, I joined Coast to Coast Campgrounds many years ago, with the promise that there would always be a place for me to camp, even if they were full..........Big Lie! Most of their parks were so far off of the interstate, that the cost of gas to get to one, would have paid for a nearby campground. Also, the yearly dues kept going up and some of their locations were bankrupt when we got there.
As an aside, our experience with camping next to the "Big Boys" and their rolling palaces, was less than friendly. Most pulled their shades closed, cranked up the satelite dish, watched TV inside and never left their rigs to chat with a little guy, like me. Also, at 6 in the morning, they fired up their diesel engines next to me, warmed it up for 20 minutes and drove off, and gee, I never even got to meet them, as I lay there wide awake.
