The 10 Gallon and 17 Gallon Transit Undermount Water Tanks will fit on the driver's side of your van with no issues; however, we're not sure if our 10 Gallon Undermount Water Tank will fit on your passenger side with the factory running board. You will have to measure your available space on the passenger side; the 10G tank is 36" x 9.5" x 8" (Length x Width x Height). The 17 Gallon Transit Undermount Water Tank is NOT compatible on the passenger side, with or without factory running boards.
