11-Gallon Mercedes Sprinter Undercarriage Water Tank (SP-UC-11)

11-Gallon Mercedes Sprinter Undercarriage Water Tank (SP-UC-11)

Claim the unused space under your slider door without drilling a single new hole in your floor. This tank mounts between the Sprinter's frame and the passenger-side slider door step cutout, using otherwise wasted undercarriage space. Ideal as a dedicated grey tank paired with a larger fresh water setup, or used standalone 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.
