As I mentioned on another thread, my boyfriend and I are planning a 4 month road trip around the USA. We've budgeted to camp 2 out of every 3 nights, and had costed the camping at $15 per night. However, I'm now thinking we may have budgeted too low, so I was thinking about taking out membership of one or maybe two camping clubs. Would this be a good idea, and which would be the best? I've seen Happy Camper mentioned here. Which other one would be good? We'll need as wide a distribution of campsites as possible, so that we can always be aiming for a discounted place to stay.
And, do all campsites have tent or car spaces; or are some for RVs only?
