And sometimes like my 2010 2501ss, it is covered up by the underbelly...this is the message I got from the product rep at forest river when I emailed him.
The slide out motor is located underneath the trailer, about in the middle of where the slide out is. You may see a slight bump or you may be able to run your hand on the underbelly and feel it. There is also a good chance that there is an access hole already cut into the underbelly for access to the slide out motor. When you get to it, there will be a ¼” hex bit in one end that is held in by a sticker. You can insert that bit into a cordless drill to manually extend/retract the slide.
I don't have a hole so I just know that I will have to cut one if I ever need to manually retract it.
