I joined Recreation USA last year. Though we're just part-timers now, it's already paid for itself many times over. They have many $10/night campgrounds with full hookups and unlimited stay in their system. I was able to find a nice $10/night full hook-up campground in Cherokee, NC during color season last year. Passport America's Smoky Mountain campgrounds all had the entire month of October blocked out.

If we were using them exclusively when fulltiming this would reduce our "rent and utilities" to only $300/month. That's cheaper than most monthly rates and we can stay however long or briefly we'd like. To put things in perspective, that's about what I currently pay each month in property taxes alone. Looked at another way, it's less than my S&B's monthly electric bill for: rent, electric, water, garbage disposal, sewer, property taxes, yard maint., pool and recreational facility maint., etc. True, some campgrounds are nicer than others, but we've been impressed with their overall quality. Most have much less restrictions than the other club's campgrounds too.
