My Dad drove a Dodge PowerWagon throughout the European theater in WWII. He was in the Battle of the Bulge, France, Belgium, Germany, the whole deal.
He was with an outfit that gathered intelligence. This was before the days of satellites and drones. They would plant microphones and determine where enemy forces were firing via triangulation and such.
I saw a group of PowerWagons up in the Ouray/Telluride area a few years ago. They are awesome rigs.
