i dont know the specific folks you're looking for, but i think in general you'll find these folks in at least every other campground spot. I too have found other RV'ers to be kind and helpful, lending a hand or whatever they can help with when needed.
Its nice you're trying to find them, and welcome to the forums. before buying our airstream we had never RV'ed before either. We love it and hope you will too!
Are you thinking of getting an airstream?
