Heavy Duty Autocar On-Off Highway Dump Truck
In the mid 1950s Autocar offered rugged "pit fenders" for their on-off road contractor's trucks. You'll also notice the belly pan guard to protect the engine. Toward the end of the 1950s a more efficient higher capacity radiator was an option. This was mounted outside outside the sheet metal and is generally referred to as a "hard nose" either on Autocars or Macks
The body here is a Marion 13 foot long 12 yard capacity part number 26288, the truck is number 95130.
