Ute and 4WD Water Tanks

4WD Water Tanks for Utes, Trailers, and Campers

Travelling off-road means being ready. A good 4WD water tank gives reliable storage for showers, cooking, or washing up when you’ve left the grid. With smart design, you get water storage without losing useful space.

From 18L up to 200L, our range includes tanks for under-tray, spare wheel, headboard, footwell, and flat vertical installs. These options make the most of unused zones in your ute, caravan, or trailer.

Built for Australian Conditions

A 4x4 water tank is built to cope with rough tracks and long journeys in the great outdoors. Constructed from heavy-duty polyethylene, automotive water tanks are designed to handle vibration, dust, and changing terrain.

Smaller portable tanks are easy to move and strap down, while larger units provide additional water for extended travel. Many designs include a breather for smooth filling and draining, giving you easy access to vehicle water supply wherever you go.

What Else You Might Need

• 12V water pumps: A 12V pump gives consistent pressure, making it easy to run taps or set up a quick shower at camp.
• Fresh water hoses: Fresh water hoses connect your tank to pumps and outlets, built to resist kinks and keep water flowing smoothly.
• Water filters: Inline filters reduce sediment and enhance fresh water, protecting both your tank and plumbing.
• Jerry cans: Jerry cans can store extra water for longer trips.
• Shower kits: Shower kits connect to your pump or tank, providing quick washdowns and comfort on the road.

FAQ About Water Tanks

How much water should I carry?

Plan 4–6 litres per person per day. A 40L tray water tank suits a weekend trip, while an 80L or larger unit works for long drives in a ute tray, caravan, or trailer where extra vehicle water storage is needed.

How do I keep water fresh?

Flush the tank before travel, fill with a clean hose, and use a breather or inline filter to maintain the water supply. Keeping hoses capped also helps avoid dust or grit when the tank is stored in a 4WD or truck.

How do I clean the tank?

Drain the tank fully, rinse with mild detergent or soap, then run clean water through hoses and outlets. Leave it open to dry for storage between trips and to prevent build-up inside your automotive tank.
