I bear to differ on that. My Dad had a 48 model 1/2 ton with a flathead six. I rode in this when I was a kid. My uncle bought when my Dad passed. One of the many JobRated Trucks that He used to haul MOPAR cars to dealers from the factories. The 1st V8 one had a 331 Hemi. The 55 that He bought new had a 354 Hemi. I have pics. My Dad was a camera nut so I have B&W dated pics. I have a pic of that truck with the car that I would eventually come home from the hospital when I was born sitting on top in the front with him standing in front of it & the factory is in the background. December 23rd 1955. I still own the car. A 1956 Tri-Color Coronet Royal. When I was born He came off the road He sold the 1st V8 one & the 354 truck He spotted trailers in his spare time & uesd it to pull stumps. Eventually it was sold & being a kid I couldn't keep up with it. I have pics, when I get to them I'll scan a bunch of them. I have a bunch of photos from the factories in Detroit & Delaware too.
