Hello ScMaDnEsS,
I know that a pickup bed was available for the Art Deco one tons because I've seen at least a couple of them in my travels. I believe Jim Carter may have a restored example in his personal collection. Matter of fact, I've also seen literature showing a pickup bed for a short (134 1/2") wheelbase 1 1/2 ton.
Welcome to the Stovebolt.
