I am a little confused on what is being identified.
The first link is of 1950 or later A-D panel trucks (number of planks is a give away, earlier years had 13 boards and 12 "skids" ). The rear truck looks like a 1-ton.
Bill's link is to an A-D Suburban, which only came in 1/2 ton. It is a pre-54/55 Chevrolet/GMC dash.
