What do RV dump stations charge?
| Fee tag in OpenStreetMap | Stations |
|---|---|
| Tagged free (fee=no) | 175 |
| Tagged as charging a fee | 148 |
| Paid, with a price listed | 67 (median $10, range $2 to $30) |

A missing fee tag does not mean a station is free. Campgrounds, private stations, and some parks often charge non-guests more than registered campers.

- Carry a portable waste tote if you boondock for several nights, so you can empty without moving the rig.

Why is a fee not listed for most stations?
OpenStreetMap only shows a fee when a mapper added one. Most listings have no fee tag at all, so 'not listed' does not mean free.
