Method of inhibiting movement of cargo during transport

A method of protecting freight in a cargo area of a freight carrier may include providing a first and second pallet in the cargo area adjacent to and spaced from each other, each pallet having a top surface supporting cargo and four side walls extending from the top surface in a direction away from the cargo; and providing pallet dunnage in the space between the first and second pallet such that the pallet dunnage contacts respective opposing side walls of the first and second pallet.
