Setting Up Your First Power Washing Trailer or Van for Mobile Service

If you’re serious about launching a power washing business, one of the most important investments you’ll make is in your mobile setup. Whether you opt for a trailer, a van, or even a pickup truck bed, how you organize your rig will determine your efficiency, professionalism, and ability to scale. 🚚💨

This article will walk you through everything you need to know to set up your first power washing trailer or van—from equipment selection to layout tips—so you can hit the road ready to clean and impress. 🧼✅

🚐 Trailer vs. Van: Which One Is Right for You?

The first decision is whether you want to go with a utility trailer, a cargo van, or even a truck bed rig. Each has pros and cons:

Option	Pros	Cons
Open Trailer	Easy to access, modular, expandable	Exposed to elements, takes up more space
Enclosed Trailer	Secure, protected from weather, clean appearance	Heavier, can be harder to access equipment
Cargo Van	Compact, mobile, secure	Limited space, harder to ventilate
Truck Bed Rig	Great for solo ops, quick access	No room for storage or future expansion

If you’re just starting out, a 5×10 or 6×12 open trailer is a popular and cost-effective choice. Enclosed trailers offer better protection but come at a higher price.

🧰 Essential Equipment for a Power Washing Rig

No matter which vehicle setup you choose, your mobile rig should include the following core components:

🧽 Pressure Washer

Commercial grade, at least 4 GPM / 3,500 PSI
Gas-powered preferred for mobility
Consider a belt-driven unit for longevity

💧 Water Tank

200 to 525 gallons is ideal
Requires a buffer tank if your pressure washer outpaces the customer’s water supply
Poly tanks are lightweight and durable

🔥 Hot Water System (optional)

Necessary for grease, gum, oil stains, or commercial cleaning
Typically mounted inline with the cold-water unit

🧯 Hose Reel System

At least 100 feet of high-pressure hose
Ideally mounted on swivel reels
Include a separate garden hose reel for water supply

🧼 Chemical Tank(s)

Designated tanks for bleach, degreaser, or surfactants
Use proper plumbing and downstream injectors

⚙️ Other Accessories

Surface cleaner (20-inch minimum)
Extra spray tips and nozzles
Wand extensions
PPE (gloves, goggles, mask)
Fire extinguisher
Toolbox with spares

🧠 Pro Tip: Avoid overloading your trailer with unnecessary gear early on. Stick to the basics and expand as needed.

🔧 Equipment Layout: Space and Workflow Matter

Efficient layout = less wasted time = more jobs per day = more money 💸

Here are some layout best practices:

Mount pressure washer closest to the tailgate or door for easy servicing
Place hose reels near the edge for fast deployment
Water tank centered over the axle for weight balance
Chemical tanks near the rear but shielded from sun exposure
Surface cleaner mount on wall or under the rig if space allows
Install shelving for chemicals, towels, and parts

Sketch out your rig layout before bolting anything down. You want to move left to right or front to back during setup and breakdown—no zigzagging!

🔋 Power and Drainage Considerations

⚡ Power:

Most gas-powered washers don’t need onboard electricity, but you may want a small generator for:

Lighting inside enclosed trailers
Electric hose reels
Battery charging stations

🚿 Drainage:

Make sure your tanks are fitted with:

Overflow shut-off valves
Drain valves for quick emptying
A filter system to catch debris

Proper drainage also helps with winterization and maintenance.

🔐 Security and Storage

If you’re parking your trailer or van outdoors overnight, theft becomes a real concern.

Secure your equipment with:

Heavy-duty padlocks
Trailer tongue locks
Enclosed trailers with reinforced doors
GPS trackers for vehicle/trailer recovery
Visible branding—thieves don’t want attention

🧠 Insider tip: Keep serial numbers of all your equipment. Insurance claims go much smoother with proof of ownership.

🏷️ Branding and Presentation

Your mobile rig isn’t just a workspace—it’s a rolling billboard.

Use high-quality vinyl graphics or magnets with:
- Business name
- Phone number
- Website and/or QR code
Keep it clean and organized—your setup reflects your professionalism
Consider adding a uniform look to your rig and your team’s attire

First impressions count, and a polished rig can win jobs before you even speak. 🎯

🧊 Weather-Proofing and Seasonal Prep

If you operate in cold climates, your rig must be ready for seasonal changes.

Install a bypass loop or recirculation system to prevent freezing
Keep antifreeze on hand during winter
Use insulated covers or heat lamps in enclosed trailers
Drain your water tanks and hoses every night during frost months

A frozen rig = no revenue. ❄️🛑

Whether you’re starting with a small open trailer or building out a full enclosed rig, focus on function, safety, and visual impact. Don’t just copy someone else’s layout—design it for the services you offer and the way you work.
