Box/Straight Trucks are a must have in the shipping industry. They have an enclosed cargo area attached to a chassis cab. Straight Trucks differ from tractor trailer trucks in that the cargo area is already attached. Traditionally these trucks are used by railways to ship the cargo, but can also be used as moving trucks or by companies to transport goods. Straight trucks have larger engines, allowing them to travel longer distances.
