Utilize the wasted space around the rear wheel wells! Add potable water storage to the interior of your rig with a universal 32-gallon water holding tank. This tank is designed to fit Sprinter 2500 & Transit (single rear wheel) vans, snugly fitting against the wall and around the wheel tubs. However, this solution can easily be adapted to fit dual-rear wheel Sprinter 3500s, Transits, and other vans (by leaving space between the tank & the vehicle’s interior wall). This tank fits on either side of the vehicle and accepts 1/2″ (black plugs) and 1-1/2″ (need to be drilled) NPT fittings. The tank measures 48″ long x 16″ tall x 16″ wide.
