Save valuable space with our Ram Promaster Wheel Well Freshwater Tank. Extra storage is key when it comes to life on the road, and that is where this nifty freshwater tank comes in.

Holding 22 gallons of freshwater goodness, these water tanks are custom-designed to fit around the Promaster’s wheel well. They can also be used in Sprinters and Transits, with a little extra room around the wheel well that can be filled easily with insulation. Believe us when we say, even with a not so exact fit, this is the most efficient use of space we have yet to find to mold to your van's lovely humps.

Key Features & Benefits:
Efficient Space Saver - One of the most awkward problems of a van build is solved immediately with our custom-made wheel well tank.
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.
Weight Distribution On Point - An often overlooked part of the equation - what if your van's weight is off-center? Uneven weight distribution can cause problems as small as some extra wheel wear, to bigger issues, like broken axles. These water tanks center the weight over your van's rear axle so you can travel down the highway stress free.
- Sound Proofing - Bonus feature! These tanks act as additional insulation when it comes to blocking road noise from your wheel wells.
Food Grade Approved and BPA Free - This should be an obvious one, but for further reassurance, yes, you can drink, shower, fill the dog bowl, or do as you please with the freshwater stored here! These tanks are food grade CSA approved! The tanks are made from linear low-density polyethylene.
