some typical scandinavian trucks would be great, e. g.
Scania 140/141: http://i53.tinypic.com/2u3za13.jpg
In 1969 the Scania 140 was the most powerful truck in Europe. It had a V8 Engine with 350HP where most of the other truck manufacturers stuck with 320HP until the mid-70ties (except Magirus with a 340HP engine).
Also the Volvo F88/89 would be a grat addition: http://www.verlagrabe.de/store/img/cms/Bilder HiK 5-2012/Volvo1.JPG
