6. International Harvester Travelette
For those who don’t know, a crew cab configuration means that a truck has four doors and a truck bed. Today, the crew cab is a common option, so most new models, full size or compact have it as standard. But, back in the day, trucks only came in a single cab configuration with two doors. Back then, no one could imagine a truck with more than two doors that could carry more than two or three people inside.
But in the early ’60s, International Harvester presented the Travelette version of their C-Series truck, which changed the industry with the first crew cab. Today, International Harvester is the famous producer of agricultural machinery and big trucks. But during those days, it was active in the pickup truck market. Their products were always heavy duty for professional users. They came with tough mechanics, big engines and durable components. The idea behind the Travelette was simple. Allow a group of six workers to travel together with their tools and equipment in the back of the truck.
