The most important membership we got first was with the Escapees RV Club (
www.escapees.com). Then we purchased memberships with Thousand Trails, Coast-to-Coast, RPI (which we dropped), Enjoy America (which we dropped), Passport America (which we dropped), and an RV Resort membership with Catalina Spa RV Resort in Desert Hot Springs, CA. Now, these are/were ours and will not fit others. They are just what works for us. I don't advocate everyone should have any of these.
