The size difference is exaggerated to those of the 1970s.
I was a ten year old when the K1500 was new.
You also have to remember that large cars like the 1979 Cadillac Deville is almost identical in length to that 2018 Silverado, and that was considerably downsized from earlier models.
The big difference in pickups happened in the late 1950s.
In the 1970s, pickups, vans and off-road machines combined made up 25-30% of the market, with commercial buyers taking the largest chunk of them.
Now they make up well over 60% of the market depending on how CUVs are classified.
