Smartbox Light Plus (2025): an enclosed box trailer with a gross weight of 3,500 kg, a 4.29 m wheelbase and an unusually high top speed of 130 km/h for class O2.
The name Smartbox describes an enclosed box trailer; "Light Plus" designates the model registered in 2025. Box trailers of this kind carry goods, equipment or vehicles under weather protection and are built in a lightweight design to allow as much payload as possible within a limited gross weight.

At a gross weight of 3,500 kg, an unladen weight of 1,220 kg and a payload of 2,280 kg, a length of 5.95 m, a width of 2.20 m and a wheelbase of 4.29 m on two axles, what stands out is the maximum permitted speed of 130 km/h, high for a trailer in this weight class; it calls for a correspondingly robust chassis and tyres.
At a gross weight of 3,500 kg the trailer stays in EU class O2, which allows an overrun brake depending on the version. The unusually high permitted speed of 130 km/h requires tyres, wheel bearings and the brake system rated for the matching speed index; the towing vehicle must itself be able to reach and permit that speed.
Buying a used box trailer of this kind means checking the door and roof seals first, since moisture otherwise enters the interior unnoticed. Because of the permitted 130 km/h, it is also worth closely checking tyre tread and age, play in the wheel bearings, and the coupling together with the jockey wheel, as these parts carry a higher load at this speed than on an ordinary 100 km/h trailer.
