Dunn & Watson currently provide 4WD water tanks designed for installation under your vehicle in volumes ranging from 65L, 80L, 100L and 140L. These roto moulded water tanks are built for Australian conditions and are trusted by some of Australia’s largest caravan and camper trailer manufacturers. They are so tough that you don’t need to install straps or bash plates to protect them from accidental damage or punctures caused by coming into contact with rocks or chips on the road.
Built at our Brisbane factory, the tough poly walls of these water tanks normally fluctuate between 5mm to 8mm thick prior to installation. Depending on the environmental temperatures, the thickness of these walls can vary between 9mm to 12mm once installed, providing all the on road protection you need to travel off road for extended periods of time. They are perfect for 4WDs, camper trailers and caravans and the water is potable.
All these 4WD water tanks come with a fill up and overflow hole on the front of the tank and a drainage hole at the rear. The rear drainage hole can be used to attach a second tank or to simply drain the water. Once installed, all you need to add is a water pump for easy access to the water, not forgetting a lockable water filter cap for additional security.
The dimensions of the 65L tank are 810mm long x 610mm wide x 200mm deep; 80L tank is 810mm long x 610mm wide x 250mm deep; 100L tank is 1200mm long x 700mm wide x 180mm deep; 140L tank is 1500mm long x 700mm wide x 180mm deep.
