Black 20ft modular cabin trailer chassis in three-quarter view

Trailer systems / Factory reference 233

20ft Modular Cabin Trailer

A welded 20ft chassis reference for modular cabins, studios and project-specific builds, with electric drum brakes and stabilising support points.

The platform

Start with the load case, not the catalogue label.

This chassis is a preliminary factory reference. A suitable package depends on the completed module, actual mass, load distribution, mounting method, towing arrangement and the Australian approval pathway.

Manufacturer terminology and dimensions are retained for review. They are not a statement that a completed trailer-and-cabin combination is registered or approved for Australian road use.

Deployment reference

See the chassis before the cabin changes the picture.

The extended support arrangement is useful for discussing placement and stability, but support-leg quantity alone does not determine foundation or occupied-use suitability.

Project fit

Three checks before this becomes your trailer.

01

Match the module

Confirm the completed cabin mass, mounting points, centre of gravity and required clearances against the chassis design.

02

Resolve the road package

Check axle loads, coupling, braking, tyres, lighting, dimensions and the intended towing and registration pathway.

03

Confirm the documents

Review current drawings, test evidence, VIN pathway, import approval and RAV requirements before supply is committed.
