This app is great, it could be better if it included membership or associations that provide RV parking. I am a member of several of these associations.
The Elks, the Moose, the American Legion, Harvest Hosts.
There is an Elks app that provides Elk locations with RV parking info. The Moose is a little more challenging, but some locations are available via AllStays Camp & RV. The Legion is also a bit cumbersome to find on the web. And harvest Hosts has a good member locator, but no routing option.
Having these data points added to Roadtrippers would be awesome. It would eliminate the flipping back and forth between apps and adding addresses manually.
