Abstract: A partition system for the bed of a utility vehicle includes a divider frame with first and second opposing side edges and a bottom edge. At least one extendible bumper extends from the first opposing side edge of the divider frame. At least one opposing bumper extends from the second opposing side edge, and at least one storage container is mounted to the divider frame. Preferably the divider is in frictional engagement with the sides of the bed of the utility vehicle and includes a plurality of mounted storage containers. In some embodiments, the frictional engagement is achieved with spring biased bumpers, and in other embodiments handle and gear arrangements are used. The divider is removable and may be placed in a predetermined location to act as a mobile storage container. A parallel brace may be used to hold subpanels in place between the divider frame and the brace. Additionally storage containers may be mounted on the removable subpanels.
