Water is a key ingredient to any custom build. RB's Sprinter Van over fender water tank stores 20 gallons of water. This compact tank design allows for more usable space in your van. Each tank comes with pre installed fittings so the tank can be mounted on either side of the van. #rbcomonents #rbadventurevans #water #camping #shower #adventurevan #sprintervanconversion #vanconversion #diyvan
