Back when I was searching for camping groups I did come across some family groups. I had the opposite problem trying to find a local group that wasn't a family group but that was more interested in the laid back life of camping, not sport activites.
Depending on which words you use in searching can bring up different results. Hopefully others here can offer more help.
Great choice for "Living within my means" and camping for one...
