Can I add fittings to my water tank?
We can't add any additional fittings to your tank as they are made in batches. The fittings are spin welded on requiring specialized equipment. There is likely a spin welder in your local area that can add additional fittings for you if needed.
What is the water tank wall thickness?
The standard wall thickness of our water tanks is approximately 3/16”.
Is this tank compatible with a water level sensor?
Yes! Check out our KUS Water Level Sensors and Gauges.
Yes!

Space is valuable inside a campervan. Each tank is 3D modelled to fit perfectly around the wheel wells of your van.
Wheel wells are awkward and difficult to build around. Usually, they end up getting boxed in. Why not use that space for water storage?
Made from food grade and BPA free polyethylene - the tanks are both approved for drinking water in the US and Canada. The threaded inserts are professionally spin welded into the tank and are guaranteed to never leak.
Speaking of leak-free, the walls are thick and durable. Made from 3/16" polyethylene these tanks can take a beating will last longer than your van will!
Distributing weight over your wheel wells will help increase traction in slick terrain. If you've ever driven an empty cargo van you will know how cautious you need to be on wet and icy roads.
Good service.
Yes, it's BIG as one reviewer noted (and I honestly don't understand how one could order something knowing the dimensions and then complain that it's too big). I don't think there's much difference between the Transit/Sprinter/Promaster tanks as they are all the same overall dimensions (16.5x19x45). But it fits well if your plan is to build a box dinette seat and/or box over it (Ours is built in with most of it under a 30" wide dinette seat that runs north/south widthwise). A 16" level probe fits perfectly in the topside 1 1/4" fitting, but note that a remote gauge will not read linearly due to the cutout shape of the tank, 1/2 full indicated on the gauge in ours is only 10 gallons or so due to tank shape. Can be oriented either 16.5 high or 19" high. 32 gallons of water is a godsend if you boondock a lot, and as you have a dually your suspension will easily handle it (Put your batteries and inverter/charger on the opposite side). I would give it 5 stars if it had a cleanout hole/fitting that I could get my hand in to scrub it out if needed. But it's a solid 4 1/2 stars.
Can’t wait to install it,😎👍
