The problem with the Maverick (as others have mentioned) is that they squander valuable bed space by adding a cab to the design.
To me, a pickup truck is a pretty utilitarian thing. I don't need a cab. I have other vehicles if I need to take passengers.
I remember pricing out a pickup a few years ago, and it was hard to find one that wasn't already configured with a cab. I guess the market demand is larger for people who have kids but still want a pickup for whatever reason.
