The truck-and-drawbar combination (also called “jumbo” or road train) offers a large volume in a single run, split between two bodies. It suits bulky, light goods, but less so long items or manoeuvring in tight spaces.
Practical reference values. We confirm the exact dimensions in the quote. Honexpres organises transport with this vehicle, on request.
