Hi and Welcome! Last Spring we camped at Lake Oconee near Greensboro, Ga. Very pretty area. We haven't done much with Good Sam's as we are part of a reciprocal membership program and often camp in those CG's. I do know folks that have enjoyed the Good Sam's system though.
We used to be part of the Casita forum when we owned one of those, and there was a huge following on that site. I too hope that the Jayco Forum will grow!
