HA! that's the term I was trying to use. the SHELF!Ahh, but the shelf is not in the cab. It is above and completely separate from the cab. It is only accessible from, and therefore an extension of, the cargo area. And, unlike the cab, it’s only purpose is storage.
btw I ended up gluing two furing strips (2x1) together. They're each technically about 3/4 inch thick. It doesn't seem to be hanging to low from the liner on top of the shelf . Ill taking photos so help give an idea.
