You can’t buy one because it has never existed, no truck ever had a 40/60 cab to bed ratio except for custom jobs made from using the front of a van with a truck bed.
Cab over engine trucks have existed for a very long time and have models that would absolutely have ~60% of their foot print be bed
CoE pickups haven’t been a thing outside of commercial vehicles for decades, hell, the VW vanagon might have been the last one in the 80s for the North American market…
Look at the original post, none of them are CoE.
I responded to your comment that said they have never been a thing. never.
