Sprinter Water Tanks
Sprinter-specific tanks, moulded to the voids in the 906 and 907 chassis. The SKU code in each title tells you the fitment: SP = Sprinter, then L / R / C for left, right or centred, UC for undercarriage, ST for the spare-tire position and DU for dually, followed by capacity in gallons.
Practical guidance for a Sprinter build: a pair of 20-gallon left and right wheel-well tanks gives you 40 gallons with perfect lateral balance and no lost floor. A single 33 or 36 gallon tank is simpler to plumb but puts 275-300 lb on one side. Undercarriage tanks (11 and 22 gallon) add capacity with zero interior cost but need freeze protection.
