I learned of the RV Parky website/app today...I think it could be very handy. I like RV Park Reviews, but RV Parky easily identifies all parking/camping available in an area.
Also have this app but have found out that some campgrounds are no longer there (closed or a truck stop has been built at that location). Thank goodness we weren't pulling the camper when we were checking out cg and found it wasn't there.
Erika,
Their tech support was good during start-up and helped with a few similar issues. That's strange that you can't add a park. I have added parks in the past. Trace
