Core Equipment
Trailer-Mounted Pressure Washers
A trailer-mounted pressure washer is a self-contained rig — water tank, pump, reels, and (usually) a burner for hot water — built to tow behind a truck. It's the standard choice for a crew that needs full capability at multiple job sites in a day, without depending on a water hookup once they get there.
Why a Trailer Instead of a Skid or Portable Unit
The trailer's own tank is the whole point — it means the crew brings their water supply with them instead of relying on a hydrant, hose bib, or customer's water access at every site. Multiple reels let more than one operator work off the same rig, and the larger footprint (compared to a skid unit) supports a bigger tank and more onboard capability without eating into a truck bed.
- Crews serving multiple job sites per day with no reliable water access at each one
- Fleet washing operations that need to bring the wash system to the vehicles
- Construction and job-site cleanup where a fixed wash station isn't practical
- Operations needing more than one operator running off the same unit

Trailer vs. Skid-Mounted
A skid-mounted unit fits on a truck deck and takes up less space, but trades away tank capacity and reel count. If the job genuinely needs a bigger onboard water supply or more than one operator working at once, a trailer earns its larger footprint. See our Trailer vs. Skid-Mounted guide for the direct comparison.
Do trailer-mounted units come in hot water configurations?
Yes — trailer rigs are commonly built with an onboard burner for hot water, since the larger footprint has room for it. Cold-water-only trailer configurations exist too, typically at a lower cost.
What tow vehicle do I need?
It depends on the tank size and overall trailer weight, which varies by configuration — this is exactly the kind of detail we scope out on a quote request rather than guess at generically.
