AI summary

Methodologies, systems, and computer-readable media are provided for relocating pallets and receptacles. A shipping motor vehicle has a weight sensor within a cargo area that measures a weight of a pallet or a receptacle. A location sensor located within the cargo area identifies available storage locations within the cargo area, and a computing device equipped with a processor computes a destination location within the cargo area for the pallet or receptacle based, at least in part, on the weight of the pallet or receptacle measured by the weight sensor. An internal conveyor system located within the shipping motor vehicle receives the pallet or receptacle from an external conveyor system and automatically relocates the pallet or receptacle to the destination location within the cargo area.
