I would need to see the frame on that truck, but I suspect that truck started life as a flight line support truck at an airport or the US Air Force. It sports the same length wheel base as the trucks I saw that had a max speed of 20 -25 mph with governed engines used to tow equipment around near aircraft.
I have seen those trucks made from Jeeps, Chevy and ford trucks and even older Dodge trucks with the Cummins turbo diesels.
If someone obtained one of those units and converted it to a street legal truck, that frame might not be butchered and might actually be "original".

Interesting truck here and not my taste, but someone surely was creative.
