I suspect a $20,000 small truck was cannibalizing the sales of their $80,000 F150's so they shut it down to force people into the more profitable trucks. If Toyota comes out with a unibody small truck that gets 35 mpg or more it'll be a runaway best seller. The Tacoma was that (minus the unibody) but it kept getting bigger, heavier, with bigger engines until it costs as much and gets the same fuel mileage as a full sized truck. What's the point of it then?
A small inexpensive unibody truck with good fuel mileage that can haul 1000 lbs or so is a very practical vehicle for a lot of people. I was noticing while driving the other day that about 7 of every 10 vehicles on the road are now some sort of compact utility vehicle. There's a reason for that, they really practical for a lot of people's needs. A little truck like this is the same way.
My 92 Isuzu pickup was the best ever. Over 400,000 miles. Exhaust, brakes, oil changes, fuel pump, and ignition tuneup. Even original clutch.
