A slide-out operating mechanism (24) for a vehicle (10) having a slide-out room section (12) includes a pair of inner rails (38) slidably mounted relative to a pair of outer rails (26), which in turn are secured to the frame (28, 30) of the vehicle. A drive and support assembly (70) is mounted to each outer rail (26), and includes a bracket (74) engageable with side walls of the outer rail (26) and to which a drive gear (98) and roller assembly (84) are mounted for rotation. Each drive gear (98) engages a gear rack (46) provided on the lower wall of one of the inner rails (38), and the roller assembly (84) includes a pair of roller surfaces which engage the lower wall of the inner rail (38) on either side of the gear rack (46). A motor mount (122) is engageable with one of the brackets (74) for securing a drive motor (128) thereto. The motor (128) includes an output shaft (132) which is coupled to an input shaft (104) to which the drive gear (98) is mounted, such that operation of the motor (128) functions to impart rotation to the drive gear (98). A cross-shaft (112) drivingly interconnects the drive gears (98), such that rotation of one drive gear (98) is transferred to the other drive gear (98) to move both inner rails (38) inwardly and outwardly relative to their respective outer rails (26) upon operation of the motor (128).
