Most clubs like Good Sam, FMCA, Escapees and others have "local chapters" that meet a few times per year all over the country but not camp together all the time. Most folks simply have different plans to visit areas at different time, time to spend with family and some do caravan into a large rally.
If you want a set group of folks to camp with you all of the time. You can try joining one of the major RVing clubs' chapters in your region and start asking if anyone will be available for what you want to do.
The main deal for many RVers is they are "free spirits", do what they want, where, when and usually on their own without trailing along with someone else. Some do attend annual rallies or go on long distance caravan tours. I think most full-timers have lived on a set schedule, had a large family, worked long hours, etc. that once they head out they want privacy, quiet and sometimes total solitude.
Good luck!
