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.
Does this mean All 1947-1955 1st Advance Design Suburbans had a plywood rear floor?
Where as the
1947-49 panel truck had planks & the A-D Suburbans never had planks, only had plywood.?
As per Jim Carter below:
Panel Truck Wood Floor Changes "It appears this was the same size that was used with the flat floor board Suburban." One Piece Panel Truck Floor "It now followed the example of the Suburban by using a one piece, 5 ply floor."
