Before you go
- Opening times and fees change. Call ahead, or look for a sign at the entrance, especially in winter when many dumps close.
- “Customers only” and “private” stations usually require a fuel purchase or a campground stay.
- Potable water at a dump station is for filling your fresh tank – never use the rinse hose for drinking water.
