Utilize the wasted space around your camper van rear wheel wells to add fresh water storage with our Universal 20-Gallon Camper Van Wheel Well Water Tank (SP-C-20). The Universal 20-Gallon Camper Van Wheel Well Water Tank (SP-C-20) is designed to fit Sprinter 2500 & Ford Transit single rear wheel vans, snugly fitting against the wall and around the interior rear wheel wells. However, this solution can easily be adapted to fit dual-rear wheel Sprinter 3500 vans, Ford Transit vans, Ram Promaster vans, and other camper vans (by leaving space between the tank & the vehicle’s interior wall).
Our Universal 20-Gallon Camper Van Wheel Well Water Tank (SP-C-20) fits on either side of the vehicle and accepts 1/2″ (black plugs) and 1-1/2″ (need to be drilled) NPT fittings.
Northwest Conversions manufactures the tanks with ports on both ends and the top to help meet your layout and plumbing needs. There are additional ports on top for filling or for installing a sensor to monitor the level.
All of our water tanks are designed and fabricated by our friends at Northwest Conversions in Bellingham, Washington.

How to Clean our Camper Van Water Tanks:
Make sure you rinse the water tank before first use, as there can be plastic bits left in the tank from the manufacturing process.
You can use bleach or vinegar to clean our fresh water tanks (or you can one of our camper van fresh water tank cleaning solutions).
It’s best to clean your water tank at the start of each camping season (once a year).
Step 1: Drain tank completely
Step 2: Mix 4 oz bleach or vinegar with 1 1⁄2 gallons of hot water
Step 3: Pour bleach/vinegar solution into tank
Step 4: Fill tank with fresh water until its full
Step 5: Let sit for 12 hours
Step 6: Drain tank completely, refill with fresh water and drain completely again (you may need to repeat this rinse step a few times)
Camper Van Water Tank Venting:
Polyethylene camper van water tanks must be vented. These fresh water tanks are not designed to handle pressure or a vacuum. A vent is necessary because as the tank is filled or emptied of its liquid an equal proportion of air must be displaced simultaneously. Discharge of a water tank without a vent would cause a vacuum to occur. A generally accepted rule concerning vent size is that it should be the same size as the tank’s largest outlet.
