Claim the unused space under your slider door (or driver's side) — without drilling a single new hole in your floor.
The SP-UC-11 mounts between the Sprinter’s frame and the passenger-side slider door step cutout, using otherwise wasted undercarriage space. Stainless steel laser-cut brackets and all mounting hardware are included. Can be used for fresh water or grey water — ideal as a dedicated grey tank to pair with a larger fresh water setup.
Built from food-grade, BPA-free polyethylene and certified to IAPMO TS-4 / RVIA standards. Designed in the USA by NW Conversions, trusted on builds from solo adventurers to professional conversion shops across North America.
⚠️ 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.
