Jumbo / Road train
Also known as: Jumbo · Road train · Truck and trailer · Drawbar combination · Kamyon römork
A jumbo is a rigid truck with its own load body that pulls a drawbar trailer. Together they give about 15.4 m of loading length and around 115 m³ — the most volume on the road.

In plain words
The truck and the trailer each have a box of about 7.7 m, usually with low decks and about 3 m of inside height. The whole combination may be up to 18.75 m long in the EU. Because the cargo is split into two units, the trailer can be left at one stop while the truck goes on to another.
Jumbos are made for volume, not weight: the payload is usually lower than a standard semi-trailer. Loading takes more time, because there are two bodies to load, and some warehouses can only load one unit at a time at the dock.
Advantages
- The largest volume of any standard road vehicle.
- Two separate units, so drops at two addresses are easier.
- 38 Euro pallets in one layer.
Limits
- Lower payload than a standard semi-trailer.
- Slower to load and unload.
- Fewer jumbos on the market in some regions, so book early.
Example from real shipping
A furniture retailer ships light flat-pack furniture from Turkey to Austria. The order fills about 110 m³ but weighs only 9 tonnes. A standard trailer would need a second truck; a jumbo carries it all at once.
