Escapees also has groups and also campgrounds and coops. Many choices. When in a campground start cleaning the front of your coach and greet everyone who walks by. Do this long enough and often enough and you will have your own "club" of friends across the country.
We were sitting outside our coach with drink in hand when a couple walked by, we greeted them and before long they were sitting with their drinks in hand and we eventually decided to have dinner together. That was 6 years ago and we see each other several times a year as our paths cross.
