Yeah, I love this thing. I've been gearing up to build a model of it. I have a laptop at my model bench which shows a slideshow of cool car images (when not displaying my reference photos) and there are several shots of this hauler, some in period, that make the rounds. It's a very intriguing machine.
I believe it inspired this US based hauler. It's built using a '59 El Camino cab on a Mercedes chassis, with lots of custom fab and body work. Apparently it was a bear to drive, and without a load on back could be made to grind its front bumper on the road when hard on the brakes.
