A Contractor’s Guide to Matching Trailers to Project Demands
Not all portable trailers are created equal—and not every jobsite needs the same configuration. From a single surveillance unit to a full-service sanitation and power trailer, choosing the right equipment depends on your project’s location, duration, crew size, and compliance needs.
This guide breaks down how to assess your jobsite and pick the trailer setup that will keep your team productive and your project running smoothly.
🧠 Start With These 4 Questions
Before you browse the catalog, ask yourself:
- What services are missing at your site?
(e.g. no power, no restroom, no security presence) - Is the site remote or urban?
Off-grid trailers might be necessary in rural or undeveloped zones. - How long will the trailer be on-site?
Short-term rentals vs. long-term ownership can affect your trailer choice. - Will you move the trailer during the project?
Towable units work best for phasing jobs or multiple zones.
🚧 Trailer Types & When to Use Them
🟢 Porta Potty Trailer
✔ For basic sanitation at construction, agriculture, or event sites
✔ Choose single or multi-stall units depending on crew size
✔ Add a handwash station for food safety or health compliance
🔵 Generator Trailer
✔ For sites without permanent power hookups
✔ Choose by voltage requirements: 120V/240V for general tools
✔ Ideal for lights, tools, small offices, or AV setups
🟣 Surveillance Trailer
✔ For high-theft or off-hours activity zones
✔ Choose solar for unattended sites or hybrid for heavy use
✔ Often placed at entrances, material storage areas, or perimeters
🟤 Dumpster-Combo Trailer
