At a length of 6,780 mm and a width of 2,500 mm, the SUPER 18 is a medium-sized trailer. An unladen weight of 2,900 kg against a payload of around 600 kg gives a ratio typical of a comparatively heavily built trailer of this size, with a relatively small payload margin. Four wheels on a 4,100 mm wheelbase spread the load across two axles. The 1990 build year places the trailer before today's overrun brake standards.

For a combination with a trailer up to 3,500 kg, a category B licence is usually enough, provided the combination's gross weight does not exceed 3,500 kg; otherwise a category BE licence is required. With a comparatively heavy unladen weight and a small payload margin, precisely observing the gross weight matters particularly, since even a small overload exceeds the available payload. The overrun brake engages automatically when the towing vehicle brakes.

When buying a trailer from 1990 second-hand, the overrun brake mechanism and its linkage are among the most important checks, as is the frame for corrosion after more than three decades of use. With a comparatively heavy build, it is also worth checking the leaf springs and axle bearings for wear. Spare parts for axles and overrun brakes are usually readily available on the open commercial-vehicle parts market for this common trailer type.
