Steel Trailers Built for the Pacific Northwest

We carry a full lineup of factory-direct steel trailers, each built for a different job. All of our trailers — including Interstate, Carry-On, and Karavan models — use high-tensile structural steel rather than aluminum, delivering maximum payload integrity and long-term durability. That matters in the Pacific Northwest, where heavy rain and demanding workloads are the norm. Our regional superstore and certified service center at 20025 Mountain Hwy E, Spanaway, WA 98387 serves as the primary trailer partner for the entire Seattle metro area. Here's how our main product lines break down:

Enclosed Cargo Trailers

Built on Interstate's DuraFrame™ steel framework with Quadra-Sealed™ leak-prevention roof assemblies to keep water out, our enclosed cargo trailers work as secure, weather-protected mobile workshops. They're a go-to for electricians, plumbers, and finish carpentry crews working across Seattle's urban core and surrounding commercial zones.

Dump Trailers

Featuring heavy 10-gauge steel decks and dual hydraulic scissor lifts, our dump trailers are built for serious loads. Local excavation crews, masonry contractors, and roofers use them daily to move saturated clay, asphalt shingles, crushed concrete, and demolition debris around King County.

Utility & Landscape Trailers

These open trailers come with pressure-treated wood decks and fold-down mesh ramp gates — the everyday workhorse for landscape maintenance crews, property management teams, and outdoor enthusiasts loading up side-by-sides for a trip into the Cascades.

Car Haulers & Equipment Trailers

A low-profile chassis design and heavy-duty Dexter axles with integrated electronic braking give these equipment trailers excellent highway stability. Whether you're transporting classic cars, skid steers, or mini-excavators along Western Washington's busy corridors, they're built to track straight and stop confidently.

Trailer Financing

A new trailer shouldn't drain your working capital. We offer flexible on-site financing options to fit your cash flow, including competitive fixed rates through Sheffield Financial with no early payoff penalties. For new businesses or buyers looking to preserve their credit lines, our Rent-to-Own option requires no hard credit check, offers same-day pickup, and applies a portion of every monthly payment toward full ownership.
