Water Tank - 200 Gallon
-
The Detail King 200 Gallon Water Tank is a UV-stabilized poly tank built for high-volume mobile detailers running pick-up, van, or trailer rigs that need to push 15 to 20 vehicles a day without a mid-route refill. This is the largest tank that still fits a standard 8-foot truck bed footprint and stays under the payload ceiling of most three-quarter-ton work trucks.
Highlight specs:
- 200 gallons when full
- UV-stabilized linear polyethylene
- 3/4” NPT molded outlets (customizable)
- 3/8” wall thickness for impact resistance
- 85 lbs dry weight
- FDA & NSF approved (resin compliance FDA 21 CFR 177.1520)
- Molded tie-down slots for ratchet straps
- 48” L × 30” W × 38” H
What “200-gallon capacity” means for high-volume detailers: a full exterior wash uses 10 to 15 gallons per vehicle (more on trucks, less on sedans), which puts a 200-gallon tank at roughly 15 to 20 vehicles per fill for a single-operator route or 8 to 12 vehicles per fill for a two-operator rig running parallel work. A 100-gallon tank caps a route day at 8 to 10 vehicles and forces a top-off before the second half of the schedule. The 200-gallon is the sweet spot for shops running back-to-back fleet accounts, dealership lot details, or country-club service runs where stopping to refill costs you a full billable job. UV-stabilized poly lets you stage the tank full overnight in a truck bed without algae or mold concerns. For lighter loads or solo route days, the 100 Gallon Water Tank and 150 Gallon Water Tank are the right step-down.
Who this is for
- High-volume mobile detailers pushing 15 to 20 vehicles in a single route day
- Two-operator rigs running simultaneous wash and interior work off one supply
- Fleet-contract operators handling dealership lots, rental car returns, or country-club accounts
- Trailer-rig owners upgrading from a 100-gallon tank that’s forcing one refill per shift
Sizing guidance
- 60 gallon is right for part-time detailers doing 3-4 vehicles a day
- 100 gallon is the full-day sweet spot for solo mobile pros
- 150 gallon bridges the gap when 100 isn’t quite enough but 200 is too much truck load
- 200 gallon (this product) is for high-volume routes and two-operator rigs
- 330 gallon is for fleet-only rigs and trailer-mounted shop builds
Truck bed weight and payload planning
A full 200-gallon tank weighs roughly 1,750 lbs (200 gal × 8.34 lbs per gal water = 1,668 lbs, plus 85 lbs dry tank weight). Add hose, reels, a pressure washer, and a generator, and you can land north of 2,200 lbs of equipment in the bed before tools and chemicals.
- Half-ton pickups (F-150, Silverado 1500, Ram 1500): payload capped at 1,500 to 2,000 lbs depending on trim. A full 200-gallon tank can put you at or past the door-jamb payload sticker. Step down to a 100 or 150 gallon, or upgrade to a 3/4-ton.
- Three-quarter-ton pickups (F-250, Silverado 2500, Ram 2500): 3,000 to 4,200 lbs payload typical. Full 200-gallon tank fits comfortably with margin for the rest of the rig.
- One-ton and dual-rear-wheel trucks: no concern, full bed capacity available.
- Cargo trailers: 5,000-lb-rated tandem-axle trailers handle the load with room for extraction equipment, generators, and supply storage.
Always check your truck’s door-jamb payload sticker before mounting a 200-gallon tank. Manufacturer payload ratings already account for the curb weight of your truck plus a driver, so the number on the sticker is what you have left for cargo.

A 200-gallon tank suits high-volume routes and two-operator rigs. At 10 to 15 gallons per vehicle, it covers roughly 15 to 20 vehicles per fill solo, or 8 to 12 running parallel work. It is the largest tank that still fits a standard 8-foot truck bed, ideal for fleet, dealership, and country-club accounts.
-
Because water weight adds up fast. A full 200-gallon tank runs about 1,750 lbs (1,668 lbs water plus the 85-lb tank), and half-ton pickups cap payload near 1,500 to 2,000 lbs. Add hose reels, a pressure washer, and a generator, and you can exceed the rating. Run this tank on a 3/4-ton, one-ton, or trailer.
-
Vehicle size and condition determine exactly how much water you use, but on average you will use 10-15 gallons to wash most cars, trucks, SUVs, and vans. Most detailers wash about 15-20 vehicles on a 200-gallon fill before needing to refill.
-
No. This tank is built from UV-stabilized linear polyethylene, so you can leave water in it for periods of time without worrying about mold or algae. That means you can fill it and stage the rig overnight in a truck bed, ready for an early start, without dumping and refilling each morning.
-
Not always. Most residential and many commercial pressure washers must be force-fed from a pressurized source, so they will not draw from a tank on their own. With one of those, add an in-line pump to feed the washer. A machine built for tank-fed use, like our DK2000 Skid Mounted Unit, draws directly with no extra pump.
