Hi 3B, The truck is a flat bed. The I.D. plate on the firewall reads 2 ton max 1/2 C.W.T.
Does this match a 3/4 ton or is the hood was from another truck? It had a different gearbox in the truck. There was looked to be a small compressor on the ide of the box. And the back springs look to be too heavy for a 1/2 ton truck.
