A cargo handling device is disclosed for a vehicle. The cargo handling device comprises a base and a lower track. A traveler and a storage unit slidably engage the lower track between a proximal end and a distal end. A linear actuator displaces the traveler between the proximal end and the distal end. A telescoping actuator is pivotably coupled to the traveler and the storage unit. A contracted length in the telescoping actuator maintains the traveler abutting the storage unit during displacement of the traveler between the proximal end and the distal end. An extended length in the telescoping actuator displaces the storage unit from the traveler upon the traveler positioned at the distal end. The extended length defines a horizontal displacement and a vertical displacement of the storage unit from the traveler for positioning the storage unit adjacent the surface.
