I saw a couple of clubs like Harvest Hosts and another I can't remember so I did some googling for reviews. I came across this long youtube addressing the different clubs: RV Clubs - Which are Worth Joining? | Technomadia
It is a long video of almost an hour. I watched only half since I really need to get off the internet and do something constructive.
The couple is very interesting. They started out full-timing in a T@B, moved on to the smaller Oliver
and then to this bus conversion. They share a wealth of info on many different topics.
