Crew cab or bust

Early crew cabs 40s thru the early 60s were typically custom one offs made out of new trucks by custom coach builders. Union Pacific used these a lot. I see em pop up from time to time. Ford and Chevy crew cabs. Interesting because they used modified front doors in the rear as well, and left the vent windows in place on the rear doors. Pretty neat that what your doing in styrene is exactly what UP would order back then. Crown Steel Products in Ohio, and Stageway Coaches in Arkansas made crew cabs to order out of standard cab trucks typically for the railroad industry.

International Harvester was making factory built crew cabs since the late 50s. Dodge entered the crew cab market in 1963, Ford in the late 60s, and Chevrolet in 1973 with the introduction of the "new" body style that would tend to rust out badly very quickly LoL.
