Ram Promaster 22 Gallon Wheel Well Water Tanks

These 22 gallon water tanks are custom designed to fit around the Promaster’s wheel well, however they will work in Sprinters and Transits as well (with a little more room to spare around wheel well).

These make efficient use of the wasted space around the wheel wells. The tank leaves space for soundproofing and insulation on the wheel well if preferred.

The tanks are made from low linear density polyethylene. Food grade CSA approved and BPA free.
