Northwest Conversions 28 Gallon 2014+ Ram ProMaster Wheel Well Water Tank - Right (PM-R-28)
Optimize your van's layout with the Northwest Conversions 28 Gallon 2014+ Ram ProMaster Wheel Well Water Tank - Right (PM-R-28), engineered specifically for the Passenger Side (Right) of the 2014+ Ram ProMaster.

This is ideal for balancing weight distribution in your build or accommodating galleys and cabinet systems installed on the passenger side.
While designed for the Promaster, this tank is also compatible with Ford Transit and Mercedes Sprinter conversions requiring a passenger-side fit (note: insulation gaps may vary due to wheel well size differences).
Rotomolded in the USA from durable, BPA-free food-grade plastic, this tank is built for the long haul. It arrives with flexible port options, allowing you to customize your intake and venting setup for a professional-grade plumbing system.
