The Tuff Terrain 30L underbody poly watertank slots in beside the mudguard and turns dead chassis space into handy water storage. The tapered shape clears suspension and tyres, meaning you keep ground clearance while still carrying enough water for washing up or rinsing gear. The under-tray mount keeps weight down low and out of the way, a smart buy for work utes and touring rigs.

The tank uses extra thick one-piece poly walls that handle stone flick and road grime day after day. UV stabilised food grade material meets Aussie standards for food and water storage, made to last in harsh sun. A built-in mount setup removes the need for straps on most installs, and the tap mounting works from either side, helping you set up your gear cleanly from the bush to the beach.

Q: Can I drink directly from this 30L underbody tank?

A: The tank uses food grade polyethylene and meets Australian standards 4020 and 4070.

This means the material does not leach common plastics into stored water under normal use. Many users connect it for general-purpose water like washing and cooking prep. For direct drinking, most installers still recommend using a separate filter or potable-water treatment suited to your setup.

Q: Does the tank come pre-drilled for a tap on both sides?

A: The tank includes mounting provision for a tap on both sides.

The body has moulded locations where the tap assembly can be fitted during installation. This layout helps left-hand and right-hand hose runs on different vehicles. Check the supplied tank before plumbing to confirm exact outlet locations and thread type.

Q: What type of vehicles can this underbody tank suit?

A: The tank suits many tray-back utes and light commercial vehicles.

The shape fits beside the mudguard where there is spare space under the tray. Actual fitment depends on your tray design, chassis layout, and exhaust and suspension clearances. A qualified installer should measure the mounting spot and confirm space before drilling or bolting brackets.

Q: How should this tank be supported under the tray?

A: A qualified person must design and fit suitable supports.

The moulded form removes the need for straps on most setups, but the tank still needs solid support. Installers usually use brackets or cradles that match the flat areas of the tank. Support across a wide area helps spread load and prevents point pressure on the plastic.

Q: Can the tank be used for grey water instead of fresh water?

A: Yes, the tank can store non-potable grey water.

The polyethylene material resists common soaps and detergents used for washing. Many touring setups use one tank for fresh water and another for grey collection. Plumbing must clearly separate fresh and waste lines to avoid cross-contamination and meet local regulations.
