NW Conversions 16 Gallon Transit Undercarriage Water Tank (TR-UC-16)
The NW Conversions 16 gallon undercarriage water tank (TR-UC-16) is a flexible Ford Transit tank that fits passenger side or driver side and works with factory Transit Trail running boards. It's suitable for fresh or grey water, made in the USA by GoCode, and carried by AVC RIG.
About the 16 Gallon Undercarriage Water Tank
The 16 gallon undercarriage water tank slots under the Transit's undercarriage with three laser-cut stainless steel mounting straps, and all required hardware is included. Mount it on the passenger side under the slider door, or on the driver side next to the fuel tank. That gives you placement flexibility depending on your build layout. Use it for fresh or grey water, so it can be your main supply or your drain tank.

Note: Despite great care taken during manufacturing and fulfillment, plastic tanks can become dirty and/or scuffed in transit. This does not constitute a damaged tank. Plastic tanks can also become slightly warped, especially on the flat surfaces. This is normal and does not render the tank defective. Maintaining a completely straight/flat surface on a rotationally molded part is not always possible, but we make every effort to keep surfaces within a 1.5 degree tolerance.

16 or 20 Gallon?
Need fresh or grey water storage outside the living space? If your Transit has factory running boards or a rear passenger heater or AC unit, the 16 gallon undercarriage water tank is the flexible pick, since the 20 gallon driver side tank (TR-UC-20) does not fit those vans. The 16 gallon undercarriage water tank also works on 130", 148" and 148" EXT wheelbases. Shop more parts in Ford Transit van accessories.
