What I've always wondered is: Does the larger footprint lead directly to a taller truck?
Is is it just that an F-150 that is as tall as a 1990 Ranger would look silly or something? The 1990s Buick Roadmaster Estate is not just 17" shorter in length than an F-150 Super Cab with a 6.5' bed, but also 17" shorter in height, which makes a sharing the road with these trucks bad (even before they are raised, which seems relatively common).
My dad wanted an 8' bed standard cab for his work and got an old one with almost 200k miles and I was slightly surprised to see it wasn't a step-up cab, while it seems like all modern trucks are.
[edit]
The Roadmaster Estate is also 8" shorter in height than the Ford Maverick, despite having a longer length; granted the Buick keeps its maximum height for a longer part of the length, but it has a shorter hood, and from the cab-back the Maverick doesn't go under 50" until the bumper.
