Unimog

I don't know the vintage of this Unimog, which is another photo I originally posted elsewhere, but its a nice example of one.

The Mercedes Unimog is a great truck, one of the all-time classic trucks, really. Somewhat analogous to the Dodge Power Wagon, it was originally intended as a post World War Two farm truck designed to allow German farmers to have one vehicle that could do anything, from plowing to taking crops to market.  It's arguably the greatest series of 4x4s every made.  They've seen widespread military and industrial use.
