Abstract: An apparatus including a plurality of interconnected portable pallets on which cargo is placed and which may be selectively moved into or removed from a truck body. The pallets constitute the bed or floor of the truck and may be independently or simultaneously moved into the body of the truck or removed therefrom so that portions of the contents may be loaded or discharged from different loading docks or the entire contents of the truck may be loaded or discharged from the same dock. The cargo may be loaded on the pallet or pallets prior to insertion into the body of the truck and such cargo may be unloaded from the pallets after the truck has departed so as to reduce delay in the operation of the truck.
