GMC likes to market itself as "Professional Grade". That tagline implies that GMC trucks are built to work hard and will hold up under the stress of whatever job they do. This kind of statement is nothing new. As long as the truck could reasonably live up to the claim, manufacturers would trumpet it loudly. And some even bolted that claim onto the front of their trucks. Long before Dodge spun its truck line off to become RAMs, they built these, the Job-Rated B-Series pickup.
Job Rated was a term coined in 1939 to describe a range of Dodge trucks built for a spectrum of jobs. Lighter duty trucks would serve general pickup use, all the way up to big commercial rigs hauling or towing heavy payloads. Dodge introduced all-new trucks for 1948 with the B Series, beginning with the B-1. These trucks were improved over the pre-war design that, while visually interesting, was woefully outdated by the time it was phased out. The 1948-1953 trucks, in my opinion, are not the prettiest things out there. However, they do have a certain toughness to them.
Anyway, cool truck. It's nice to see an early 1950s pickup that isn't a Chevy.
