A 5.5 gallon shower tank — a mounted water tank rather than a carried bag.

The step up from a portable shower is not having to fill and hang anything. A tank lives on the vehicle, holds enough for several proper washes, and is ready whenever you stop.

5.5 gallons is roughly three unhurried showers for one person, or a weekend for two who are being sensible about it.

Mounting is not included and depends on where you want it — rack, bed rail or bumper. Tell us your setup and we will help you work out what you need.
