I came across a web site today that kind of specialists in caravans.
http://rvsingles.org/ One of their rules is that you don't mind being around couples, so I take it that it is open to all. The way they put it
To Join You Must Be:
★ Single
★ Responsible, Respectful, and Respectable
★ Able to be in a group where some are paired
★ You do not have to own any type of RV to be a member
★ When you travel with the WINs, it must be in a vehicle in which you can eat, sleep, cook, bathe and go to the toilet, even if all facilities are portable
What they say about themselves:
We have 60 to 120 caravans, circuits, and gatherings each year. We do a multitude of activities during our travels, such as kayaking, hiking, biking, sightseeing, zip lining, boat tours, museums, plays, factory tours, and more. Many of us love history, and we go see where history actually happened. Whatever you want to do in traveling, most likely we’re already doing it.
I looked at some of their upcoming dates and it looks like they don't boondock much. Mostly casinos and campgrounds.
