For those owning Motor Pool (3rd ed) it might help to note that a very similar vehicle was sold in the USA and abroad as the Dodge Power Wagon until 1969 and outside the USA until 1971. [Note that Dodge kept the Power Wagon nameplate until 1981, but post-'71 vehicles were different.]
While it was not a comfortable truck it was sturdy, reliable, easy to fix, and apparently very popular. (From the Encyclopaedia of American 4x4s (Krause Publications) and Wikipedia

So this would be useful to any GM's doing a 1950's scenario, or a less-economically-advantaged rural scenario right to the present day.
