Work truck: something with company decals or ladders / equipment attached. extremely broad definition

That's not a broad definition. That's quite limiting. A carpenter doing small commissions isn't likely going to have massive decals on the side.

I have got a friend whose a landscaper, none of their work vehicles have decals. Not the vans or pickups.

in what way are the graphics misleading?

Already explained this. Ford still makes single cab trucks. The graphic doesn't show that.

Seems you don't like the fact trucks have grown

I never said they haven't. Although neither did you, that graphic you showed that the actual size of one specific model of Ford hasn't changed. Just the proportion of cab to bed.

But it sounds more like you already have a world in your head, and don't like the fact the real world doesn't line up with your views.
