At a gross weight of 3,500 kg, the mobile stage has an unladen weight of 3,200 kg, leaving only 300 kg of payload. This small margin makes sense for a mobile stage, since the stage structure itself accounts for the weight and little additional load is added. Length is 11,760 mm at a width of 2,470 mm, the wheelbase is 7,270 mm on six wheels, and the permitted top speed is 100 km/h.

At a gross weight of exactly 3,500 kg, the mobile stage sits at the upper limit of trailer class O2, usually built with an overrun brake. Six wheels on a 7,270 mm wheelbase spread the weight of the unfolded stage platform along the full length of the chassis. Towing with a category B licence, the combination of towing vehicle and trailer must not exceed the permitted gross combination weight, which at 3.5 tonnes is often already reached by light trucks or heavy vans.

When buying a used mobile stage, besides the chassis, axles and brake system, particular attention should go to the folding stage elements: hinges, locks and the flatness of the stage surface should be checked. Hydraulic or mechanical supports for setting up and folding away need checking too, as do lighting, railings and fall-protection fittings. Corrosion on the chassis and drawbar, and the condition of the overrun brake, complete the check.
