A system for constructing removable horizontal decks and vertical partitions for use in a cargo holding section having at least two walls, the system comprising:
- a plurality of planar units, wherein each of the planar units includes means for supporting objects thereon when the planar unit is oriented in a substantially horizontal position;
- means for storing each of the plurality of the planar units, wherein said means for storing is formed within the cargo holding section and is formed within at least one wall of said two walls;
- means for removably supporting the plurality of the planar units between said two walls of the cargo holding section to form at least one of said removable horizontal decks;
- and
- means for removably holding the plurality of the planar units in at least one vertical position within the cargo holding section to form at least one of said removable vertical partitions.
