The Truck File is a spreadsheet that contains all the information about the fleet that will be used to make deliveries. Each row in the file represents a Truck on which the Stops can be loaded. Key fields represented in the Truck File include Capacity, Availability, and Costs. 

If you already have a Truck File or a spreadsheet with the required fleet information, it can be used in the project if it contains the required data columns. If you do not already have a Truck File, a new one can be created that will automatically populate the necessary header columns and allow manual input of all customer data.
