A method is disclosed for controllably loading a haul vehicle 110, with a payload material 115 desired by a customer, using a mobile loading machine 120. An identification tag 135, located on the haul vehicle 110, is read by an identification tag reader 140, located on the mobile loading machine 120. A haul vehicle identification signal is produced from the reading, and compared to customer data files 125. A load command signal, containing selected information from the customer data file 125 that corresponds with the haul vehicle identification signal, is produced.
