My search for a shorty D100 is over

I always wondered why Chevy and Dodge didn't make as many big block half tons as Ford did. Ford made a PILE of big block half ton trucks.
My guess would be, Ford in the day was consider "THE" work truck, with its twin tuff "I" beam suspension. Tuff truck, Big motor = sales, just like the Cummins of today in the HD Dodge (RAM) trucks.
