Custom Trailer Builds

Your trailer should be built around your needs, not the other way around. Whether you’re looking for a dependable cargo trailer, a custom car hauler, a race trailer, a contractor trailer, or a fully equipped trailer for your business or recreational adventures, Northwest Rides makes it easy to design a trailer that fits your vision, needs, and budget.

Choose your preferred size, color, exterior finish, interior options, and accessories. From upgraded flooring and wall panels to E-track systems, cabinets, lighting, additional doors, insulation, electrical packages, and custom features, we’ll help you put together the right combination of options. No cookie-cutter builds here — just trailers thoughtfully spec’d to make sense for how you plan to use them.
