We had a custom underslung water tank made for the van by Barratt Tanks. It sits neatly tucked up to the chassis rails in front of the rear axle and is no lower than the exhaust or fuel tank. It holds approx 100L of fresh water, and 45L of waste grey water. We also had a CBE water level sender fitted so we can keep an eye on water levels from inside the van.
You can see here how the brackets attach and clamp the tank. A strip of thin foam was added between the tank and chassis to stop any chaffing or vibration.
It is filled via a standard hoselock connector, and the waste is drained via the other tap. These were mounted tucked up high on the sill and the waste tap was cut down to aid with ground clearance as we often take the van up rough dirt tracks. Pipes were then insulated and secured.
The breather was also extended and fitted with a wee stainless filter to stop anything crawling in.
Also did a bit of wiring and plumbing on our secondary 10L internal fresh water system. It consists of a 12v microswitched tap connected to a Whale submersible water pump that sits in a small water carrier. ideal for a quick night away in the winter when the main system is drained down for frost, or can be used with bottled water when we have filled the the main tank from a tap we cannot guarantee is quality drinking water.
