An office container is a ground-level steel unit built on a standard shipping container frame, with HVAC, lighting, electrical, and windows. It’s secure, stackable, low-profile, and available across our full branch network. An office trailer sits elevated on a chassis with wheels, has stairs, and offers more interior layout flexibility — including larger combo configurations with restrooms. Office trailers are stocked at select branches based on regional demand, so availability depends on your location.
