The BOAB 120 Litre Rectangle Poly Water Tank (WTP120U) is purpose-built for Australian 4WD, caravan, and RV applications where maximising fresh water capacity is essential. Manufactured from food-grade, UV-stabilised polyethylene, this 120L rectangular tank is engineered for underbody or chassis-rail mounting, making use of dead space beneath your vehicle or van and keeping your living area free from bulky containers. The rectangular profile ensures efficient use of available space, and the robust blow-moulded construction handles the vibration, dust, and corrugation punishment that Australian outback tracks are famous for.

Whether you're embarking on a lengthy lap of Australia in your motorhome, tackling remote 4WD tracks through the Kimberley or the Simpson Desert, or setting up a comfortable off-grid caravan campsite for the season, this tank gives you the water reserves to stay out longer. It is ideal for supplementing an existing onboard water system, connecting to a 12V water pump, hot water system, or camp shower — anywhere reliable water storage is needed for drinking, cooking, and washing in the Australian bush. The 120-litre capacity suits couples and small families, balancing substantial storage with a manageable weight when full.
