Revell did a model of this truck

The whole of the truck was covered in decal. They've actually done 3 so far, This one, a Renault Magnum with trailer called "Ice Truck" and a Scania with trailer "Friedenfels". All were totally decalled. I haven't had the courage to try one yet.

I like your trailer by the way.
