In "my"opinion, Bob pretty much told it all. Of course there are lots of "camping or RVing clubs" out there but it's an individuals choice whether to join them or not, the benefits aren't all that rewarding. Most are misconstrued, they aren't an actual "club" per se but rather a group of like minded individuals interested in saving money on whatever expenses they encounter on the road. Escapees is an actual properly functioning RV club, designed and operated by and directly for Rver's both full timers,vacationers and weekenders. Passport America is pretty much solely a discount club for participating members and as Bob indicated it pays for itself over and over. What this boils down too is a person isn't necessarily required nor needs to join an RV club to enjoy traveling in the U.S.
