Dually Sprinter owners have been waiting years for this one! The symmetrical design of this tank allows it to fit around either wheel well with ports on either end of the tank, so it can be placed on the driver or passenger side of your van.
Looking for a grey water tank to compliment your freshwater tank? Check out our 17 Gallon Sprinter Undermount Water Tank! Need something smaller? We also have a 10 Gallon Sprinter Undermount Water Tank. These undermount water tanks fit snugly under your Sprinter's undercarriage; the perfect solution for your off-grid water requirements.
Key Features & Benefits:
- Space Saving - A unique way to make efficient use of that awkward wheel well area and shape.
- Perfectly Shaped - Not only do these tanks mold to the shape of your wheel well but the top and outside are also squared off to account for further building. Last we checked, it’s easier to build a square box than a round one.
- Build Options - These tanks are interchangeable between both wheel wells; you can fit this tank over whichever wheel well works best for your build. Need more water? Place one on either side of your van for mega-volume!
- Distributes Weight - Adds weight over your rear axle to help increase traction if you get in a sticky spot. No more slips and skids, not to mention unwanted wheel wear, thanks to the perfect weight distribution of these tanks.
- Sound Proofing - When it comes to road noise, these tanks step it up with added noise reduction around your wheel well.
- BPA-Free and Food Grade Approved - Feel safe knowing these tanks are food grade CSA approved! Wash the dishes, have a shower, fill the dog bowl, and stay hydrated, while exploring in your van!
-
