Motor stop for a through-frame slide out system

A slide-out frame assembly including a slide-out frame displaceable relative to a fixed frame, the slide-out frame assembly comprising:

• a motor including an output shaft;
• a drive system coupled with the output shaft and engaging the slide-out frame, the drive system driving the slide-out frame linearly in a first direction between an inside position and an outside position;
• and
• a motor stop mechanism acting between the motor and the drive system, wherein the motor stop mechanism includes:
• a motor mounting surface to which the motor is attached, the motor output shaft being positioned through the motor mounting surface,
• a coupler fixed to and rotatable with the output shaft,
• a threaded drive shaft fixed to and rotatable with the coupler,
• a trunnion threaded on the threaded drive shaft and displaceable on the threaded drive shaft with rotation of the threaded drive shaft in a second direction perpendicular to the first direction, wherein the trunnion is displaceable between a retracted position and an extended position by forward and reverse rotation of the threaded drive shaft, and
• a stop limit defining the extended position of the trunnion,
• wherein the extended position of the trunnion corresponds to the outside position of the slide-out frame.
