Water Tanks

Water tanks from NW Conversions for the Mercedes Sprinter, Ford Transit, and Ram ProMaster, plus the KUS level sensors that read them. Wheel well tanks hold 20 to 33 gallons, including driver, passenger, and center options for the ProMaster and a 25 gallon tank for dually chassis. Undercarriage and spare tire tanks mount under the van, and 10 and 20 gallon box tanks fit inside a galley cabinet or bench.

Water is the heaviest thing in your build, and it shouldn't cost you floor space. Each tank is shaped to room the van already has, over a wheel well, under the floor, or in the spare tire well, so your layout stays yours. They're BPA-free, food-grade, and made in the USA.

Most tanks are built for one position and one side, so check the fitment note on the product page before ordering. Pick a KUS sensor by tank height: probes run 6 to 19 inches, and many tank pages name the recommended model. Shopping for one van? See Sprinter, Transit, and ProMaster tanks, and Wheel Well Cabinets for a cabinet to build around them.
