The DEMARKO was built between 2013 and 2015 and has an unladen weight of 10,740 kg; against a gross vehicle weight of 51,000 kg, that leaves a payload of 40,260 kg. Overall length is 13,680 mm, the wheelbase 11,080 mm across 6 wheels, width 2,550 mm.
A payload of 40,260 kg on 6 wheels across three axles means a high load per axle, typical of heavy-goods transport such as construction machinery, transformers or prefabricated components. The long wheelbase of 11,080 mm spreads the weight across the full length of the vehicle and stabilises handling under such a high load.
When buying used, such a heavy air-braked semi-trailer lives or dies on the frame and the brake system across all three axles: check lines, brake cylinders and linings for corrosion, leaks and wear. Inspect the chassis for cracks and sagging after years in heavy-haulage service, along with axle bearings, tyres and tread depth, lighting and the coupling to the towing vehicle. With a 2013 to 2015 build year, it is also worth checking the service history from commercial use.

- Work the gross weight against the towing vehicle before buying.
- Compare the chassis number with the papers.
