Thanks Lang, I had not picked the outer layer of paint as Vietnam era, certainly fades to an unusual colour. Have now done a search on Aust Army Vietnam trucks/transport including Studebaker Ford and Inter but could find nothing that matched. It does not look like it would be mounted under the tray as the lid would not open, so I assume it would have to be mounted between cab and tray, or on the tray itself.
