11-Gallon Mercedes Sprinter Undercarriage Water Tank (SP-UC-11)
About the Product
11-Gallon Sprinter Undercarriage tank claims the unused space under your slider door without drilling a new hole in your floor. Mounts between the Sprinter’s frame and the passenger-side slider door step cutout, using otherwise wasted undercarriage space. Use it as a fresh water tank or a grey water tank. TEi lists it as both a potable water tank and a waste holding tank. It works well as a dedicated grey tank paired with a larger fresh water setup, or on its own for fresh water.
⚠️ Gas engine Sprinters: The exhaust runs closer to the frame on gas models. A heat shield (not included) should be installed between the tank and exhaust before use.

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.
