The PROMOSTAR RoadTrain has an impressive look. A full 28 meters in length includes attention for your brand, products and services. However, the RoadTrain doesn't always have to be set up this way; the two semitrailers can also be placed individually opposite or across corners. Or they travel to different locations separately each day and only meet for larger events. A particularly sophisticated feature is the rear lock, which can be used to connect both trailers and thus create a passageway.
