The Dorgler dates from 2001 and has an unladen weight of 10,330 kg; against the gross weight of 32,000 kg that leaves a payload of 21,670 kg. Length is 7,920 mm, width 2,550 mm and wheelbase 5,530 mm; the body stands on four wheels. The comparatively short length for this gross weight points to a compact body for concentrated rather than bulky loads.
In class O4, a multi-axle compressed-air brake system is mandatory; the overrun brake of the lighter classes is not sufficient above 10 tonnes. Towing requires driving licence category CE, and the towing vehicle's permitted towed mass must be rated for the gross weight of 32 tonnes.
When buying used, the brake system matters most: check lines, brake cylinders and linings on all axles for corrosion, leaks and wear. Chassis and frame should be checked for corrosion and cracks, as should axle bearings, suspension, tyres with their tread depth, lighting and the coupling to the towing vehicle. Exactly one example of this type is registered in the Netherlands; with a 2001 build date, it is also worth checking spare-parts availability.
