A movable storage system provides a repositionable storage location for livestock tack, including saddles and blankets. The system is particularly well suited for horse trailers and other types of transport trailers. The system includes a pivotably movable upright panel or wall that is fitted with horizontal storage arms or shelves for supporting various equipment and tack. The system can be repositioned at different angular positions relative to the upright stationary walls of the trailer, as desired. The system includes hinges coupling one side of the storage system to the trailer to provide a vertical pivot axis about which the system is pivotable. Latches are provided to secure the system at a desired angular position within the trailer. Storage compartments and gates may be included with the storage system.
