We are always striving for better space-saving ideas, and this undercarriage tank is just the ticket! This tank is designed to fit snugly around your Promaster’s framed undercarriage; these tanks are the perfect solution for your off-grid water requirements.

Composed of high-quality, BPA-free, food-grade approved linear low-density polyethylene, this tank can also function as freshwater storage. We've created a complete Freshwater Fittings Kit that includes everything you need to turn this tank into an undermount freshwater reservoir. 

Complete your off-grid water management system by pairing this undermount tank with our 22 Gallon, or our 32 Gallon Promaster Wheel Well Water Tank. Worry less about water management, and spend more time adventuring!

Key Features & Benefits:

  • Save Space - Mount underneath your van chassis for extra storage room inside your van - passenger side only.
  • Perfect Fit - Designed to fit perfectly under the Promaster van, simply position the tank and attach with strapping, no need to make modifications.
  • Durable Design - This tank is tough; rest assured knowing your tank will hold up to exposure and the elements.
  • Multi-Purpose - Use this undermount tank for grey water storage, or bundle it with our Freshwater Fittings Kit and turn this tank into a freshwater reservoir.
  • BPA-Free and Food Grade Approved - These tanks are CSA approved and food grade certified for safe drinking water.
  • Compatible - This tank pairs well with our 22 Gallon and 32 Gallon Promaster Wheel Well Water Tanks.

Dimensions & Specifications:

Designed for the Ram Promaster 159" & 159" extended wheelbases.
NOT COMPATIBLE with the 136" wheelbase.

The tank can only be mounted on the PASSENGER SIDE of your van.
However, your drain hose can be routed to your drivers side if needed.

NEW! Tanks are now made from linear low-density polyethylene.
Food grade CSA approved and BPA free - safe for freshwater use!
