For a ProMaster van build, the space under the floor is prime real estate for water. This 36 gallon undercarriage tank is sized to serve as a fresh or grey water tank, which keeps the weight low and leaves the cargo area free for the rest of the build.
The tank is listed as TEI tested and listed, RVIA approved and BPA free, which is the paperwork van builders and inspectors ask about. Dimensions are approximate and can vary by up to half an inch, so leave a little margin in your layout and plumbing plan.
Fitment
Listed for Dodge / Ram ProMaster vans in the 159 and 159 EXT configurations, model years 2013-2024. The vendor title names the ProMaster 2500 and 3500; the vendor handle also lists the 1500, so confirm your exact van with us before ordering.
Questions before you order?
Fitment questions are easier to settle before the box ships. Call or text Carl & Anton at (920) 249-7744 or use the chat — real humans in Sheboygan, Wisconsin, not a call center.
