I've been a member and used their mail service since 2010. They are certainly great for full timers.
If you're looking to recoup your dues via discounts at their RV parks, be sure to check out the details on where they are located and how what they offer might fit into your needs. Again, their parks are great and members can stay for less than $100/week, but there aren't that many of them when compared to some other CG chains.
They do, however, serve the broader RV community via lobbying, etc.
Best of luck.
