The Tuff Terrain Underbody Poly Watertank 18L Headboard gives your truck a fixed 18 litre water stash without stealing tray space. The slim 120mm body tucks up against the headboard and keeps the centre of the tray free for gear and pallets. The left side mount point keeps hose runs simple so you can get out there and wash up between jobs. The underbody position also drops weight low which helps the whole setup feel more stable on rough access roads. The hand cleaner port at the front keeps quick wash ups in easy reach.

The tank uses Australian food grade polyethylene that meets AS 4020 and AS 4070 so you know it plays nice with water and food contact. UV stabilisers help the plastic tackle harsh Aussie sun from the bush to the beach. Extra wall thickness helps the tank handle stone flick and day to day knocks under the tray. The one piece mould means no seams to crack over time which is a smart buy for long term use. A simple rectangular footprint keeps bracket fabrication and plumbing straightforward for your fitter.

Does the tank need support straps to mount?

No in most applications the tank does not need separate straps because the moulded form sits directly on brackets or a cradle. The installer still needs to confirm the structure on the specific vehicle. A qualified fitter can decide if extra straps or clamps are required. Their decision should follow local road rules and engineering practice.

Can this tank store non potable water only?

The tank uses food grade polyethylene that meets AS 4020 and AS 4070 so it can hold potable or non potable water. Many operators still dedicate one tank per water type to avoid cross contamination. Labelling the plumbing clearly helps separate drinking and wash water systems. Cleaning routines should match the intended water use.

Where is the best place to plumb the outlet?

Most installers run the outlet to the rear or side of the tray for simple access. The exact outlet path depends on tray layout toolboxes and step positions. Straight hose runs reduce pressure drop and snag points. A ball valve mounted near the outlet point usually gives the operator better control.

How often should the tank be inspected?

A visual inspection every few months suits most commercial use. Checks usually cover mounting brackets hose connections and any abrasion points. Interior checks after draining help pick up sediment or growth. Regular inspections let you fix small issues before they damage the tank or plumbing.

Can the tank be removed after installation?

Yes a qualified person can unbolt the brackets and disconnect the plumbing to remove the tank. Allowing full drain before removal makes handling simpler. Recording hose routing and valve positions helps refit the gear in the same orientation. Rechecking all connections after refit keeps the setup working as intended.
