The AD 3502 was built in 2003 and has an unladen weight of 1,475 kg; against a gross vehicle weight of 3,500 kg, that leaves a payload of 2,025 kg. It runs on 6 wheels with a wheelbase of 4,790 mm and a width of 2,100 mm.

Six wheels on three axles at a width of only 2,100 mm gives a narrow, multi-axle design of the kind used for long or unevenly distributed loads at a limited axle load. The payload of 2,025 kg amounts to nearly two-thirds of the gross vehicle weight, which across three axles means a moderate load on each one.

When buying used, a three-axle trailer in this class lives or dies on the override mechanism: it must compress and extend smoothly, with no play or corrosion in the guide. The checklist should also cover brake cables, linings and the reversing lock, all three axle bearings, tyres and tread depth, the frame and floor for rust or damp, and the lighting. With a build year of 2003, also check the spare-parts supply for brakes and axles, as well as the condition of the suspension after years in service.
