The Hot2Go T185SKH-SK40004HH is a complete 4,000 PSI, 3.5 GPM hot-water pressure washer trailer package built for contractors who do mobile heavy-duty cleaning. The unit pairs a 389cc Honda GX390 electric-start engine and an AR triplex pump with a diesel-fired 12 VDC burner that heats water up to 250 degrees Fahrenheit, then mounts the whole works on a 200-gallon water-tank trailer with hose reel, torsion axle, and DOT lighting. Mobile contractors, fleet washers, restoration techs, and oilfield service operators choose this class of trailer when their work happens at customer sites with no water supply and no power.
Use cases
- Fleet truck and tractor washing at customer sites with no water hookup
- Grease and oil removal from commercial kitchens, food-service drive lanes, and dumpster pads (hot water is essential)
- Heavy-equipment and construction-yard cleaning on remote job sites
- Oilfield service work cleaning pumps, valves, and rig equipment
- Mobile detailing of large vehicles, RVs, and motorhomes
- Sidewalk and dumpster-pad degreasing for property management routes
- Restoration and fire/flood remediation where temperature speeds cleaning
Why hot water and a self-contained trailer
Hot water cuts grease, oil, and protein soils that cold water cannot touch at any pressure. The integrated 200-gallon water tank means the operator does not need to source water at the customer's location, and the 16-gallon diesel and 1.6-gallon gas tanks support a full work day in the field before refueling. The 3,700-pound torsion axle handles the loaded trailer weight on rough job sites, and the hose reel keeps 50 feet of hose organized between stops on a route.
Frequently asked questions
What does the diesel burner actually do?
The 12 VDC diesel burner heats water passing through a stainless-wrapped 1/2-inch SCH-80 coil up to 250 degrees Fahrenheit. The hotter the water, the faster grease and oil release. Burner ignition is operator-controlled; you can run cold water for soap application and rinse, then engage the burner for the wash pass.
Is the trailer DOT compliant for towing?
The trailer ships with DOT lighting, 3,700-pound torsion axle, and standard 2-inch ball coupler. Compliance for plates, registration, and tow vehicle requirements varies by state; check with your DMV before highway tow.
What water-supply options work with the 200-gallon tank?
The tank is 200 gallons of seamless polyethylene with a 3/4-inch 80-micron inlet filter. Refill from any standard water source: house spigot, municipal hydrant (with permit and meter), commercial bulk water, or even a pond if you add an extra filter. The pump pulls from the tank; you never have to feed the pump directly from a city supply.
How long does 200 gallons last on a typical job?
At 3.5 GPM the tank gives roughly 57 minutes of continuous trigger time. On a typical wash route with intermittent triggering, that translates to two to three hours of work per fill. Mobile operators usually plan a midday refill at a known water source.
What about freezing climates?
Winterize the pump and coil with antifreeze before the first hard freeze. Some operators run a small auxiliary heater in the pump enclosure on overnight stops below 25 degrees Fahrenheit. The trailer is built to be operated in cold weather, but the pump, hoses, and coil have to be protected from ice formation.
What is the warranty?
Manufacturer warranty covers the AR pump for 5 years, the Honda engine per Honda's commercial warranty, the burner components for 1 year, and the trailer frame for 1 year. Damage from freezing, running the pump dry, or improper diesel fuel is excluded.
