Build the trailer around the job

Trailer options

Choose access, power, lighting, storage, climate, plumbing and running gear as parts of one working configuration.

Configure with intent

Don't start with a shopping list.

Options work together. A generator affects storage and weight. A large side door changes cabinetry. Water capacity affects payload and space. Tell Universal what the trailer needs to accomplish, then use these proven options to shape the solution.

Common questions

What buyers ask before the build.

Do I need to choose every option before contacting Universal?

No. Start with the mission, payload, people, equipment and towing plan. Universal can help identify the options that support those requirements.

Can options change the trailer's payload capacity?

Yes. Cabinets, generators, tanks, lifts, appliances and other installed equipment add weight and can affect balance. They should be considered with the complete loaded configuration.

Are options limited to the items shown here?

No. This page preserves the established option categories from the existing site, but Universal also evaluates specialty requirements during project planning.
