Your question made me curious so I researched some more..... RoadPass made an announcement back in 2021 about adding Campendium to their .... product line of apps. In that announcement, they stated, "Roadpass Digital is a technology joint-venture between THOR Industries and Tourism Holdings Limited. Roadpass Digital is focused on making it easier to experience, own, and maintain recreational vehicles as well as more easily discover, book, and navigate road trips. Roadpass Digital has offices in Chicago, Cincinnati, and Auckland. Learn more about Roadpass Digital and its Campendium, Roadtrippers, RVillage, and Togo RV products at roadpass.com."
If you click the links in their announcement, you will find that "As of March 31, 2023 the RVillage website and mobile apps are no longer available and end user support for those products has ended." Also, for the Togo RV, "No more switching between apps. Togo RV is now integrated into Roadtrippers Premium!" (in other words, you have to buy the premium version to access it.) And RoadTrippers is "based on what we've learned from over 38 million trips" and "AI-base Autopilot"....
Here's hoping that the continued use of Campendium apps prevents them from killing it off.
