Abstract

A sliding bed extender arrangement is provided that basically has a vehicle cargo area, a pair of roller tracks, a pair of mounting arrangements and a bed extender. Each of the mounting arrangements has a pair of rolling members and a locking mechanism that are disposed in one of the roller tracks. Each of the mounting locking mechanism has a locking member slideably disposed in one of the roller tracks and a first hand operating portion operatively coupled to the locking member to selectively lock the mounting arrangement. The sliding bed extender has a generally U-shape as viewed from above with first and second side ends rigidly attached to the mounting arrangements to extend across the vehicle cargo area.
