11-Gallon Mercedes Sprinter Undercarriage Water Tank (SP-UC-11)
The 11 gallon Sprinter undercarriage tank (SP-UC-11) claims the unused space under your slider door without drilling a new hole in your floor. AVC RIG carries this NW Conversions tank from GoCode.
About the 11 Gallon Sprinter Undercarriage Tank
It mounts between the Sprinter's frame and the passenger-side slider door step cutout, using otherwise wasted undercarriage space. It is ideal as a dedicated grey tank paired with a larger fresh water setup. It can also be used 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.

Planning Your Water System

Shipping and Lead Time
Ships in 1-2 business days.
Note: Despite great care during manufacturing and fulfillment, plastic tanks can get dirty or scuffed in transit. This does not mean the tank is damaged. Plastic tanks can also warp slightly, especially on flat surfaces. This is normal and does not make the tank defective. A perfectly flat surface on a rotationally molded part is not always possible. Every effort is made to keep surfaces within a 1.5 degree tolerance.
