I was checking out a website about 1963 Dodge Trucks (link to site no longer active) and I came across the Swamp Fox Army Truck!
This special Dodge Power Wagon, Series 300, was a unique 1-ton truck. Massive low pressure tires called Terra-Tires, gave this Dodge Power Wagon W-300 “Swamp Fox” maximum traction in the most difficult terrain. The front tires were 46x 18x 16 R Goodyear Super Terra-Grips while the rear ones were 46x 24x 16 R. This specially designed vehicle was one of the first all-terrain vehicles to emanate from one of the Big Three.
look closely at the fender emblem, reads GM Diesel…..
Weird, but it is definatly a Dodge body….
