The register lists 6 versions with kerb weights from 2,120 to 2,960 kg at a uniform gross vehicle weight of 3,500 kg. Widths range from 1,640 to 1,840 mm.
With a gross vehicle weight of 3,500 kg throughout, the ET range falls into the European vehicle class O2, which can be towed on a car driving licence with the BE category; that makes trailers of this class a common market segment for both private and commercial users, between small single-axle trailers and heavy semi-trailers. Trailers of this kind are typically sold through regional dealers and general trailer-accessory networks rather than direct factory sales.
When buying a used trailer of this size, the frame and drawbar, coupling head and jockey wheel, and the brakes and lighting are the main points to check. Corrosion on the side walls and load floor, tyre and axle-suspension condition, and the tightness of any tarpaulin or side panels should also be inspected; spare parts for trailers of this weight class are widely available through general trailer-accessory suppliers.

What to check before buying
- Search the frame and welds at the axle mounts — that is where cracks start.
- Check the brakes and the last inspection in the papers.
- Work the gross weight against the towing vehicle before buying.
- Compare the chassis number with the papers.
- Look at the floor, cover or body from the inside — rust does not show from outside.
