How did you come up with these numbers? Very wide gap between the two.
Well, Ford sells F150s from the high Can$60K down to Can$25K in a stripper, reg cab (even with manual roll-up windows). So I wouldn't be surprised at that big a differential.
It's the high end, the luxury truck market, that has exploded over the last couple of decades and is where the manufacturers are making most of their money. Esp. Ford. I'm sure Nissan will target that market.
And all the manufacturers still make work trucks, but you will have a hard time finding them on the lots of urban and suburban dealers. Maybe out in farm country. Otherwise you have to order them. Hopefully Nissan will do the same. They make the NV series Delivery Trucks, so why not?
