Common questions

How do I show only RV dump stations on the map?

Open the map and tap the RV dump & water button (or open Filters and switch on RV dump & water, then press None for the other types). The link below opens the map with only the RV layer on.

Where does this RV data come from?

RV dump stations and water fill points tagged in OpenStreetMap, plus federal campgrounds and recreation sites whose Recreation.gov (RIDB) description lists a dump station. Commercial RV apps are not copied.

Is every dump station open to the public?

No. Some are for registered campers or fuel customers only, and many close in winter. Each listing shows the access and fee notes our sources give; confirm with the site.
