Mike, ... my 2008 Monaco has a cable slide that may be the same. My 2007 had the same cable slide as the 2008.
The maker is Accu-Slide. The cables, pulleys, and motor are inside the coach above the slideout in the wall behind the fascia of the slideout. The slideout fascia must be removed to access any of the mechanism.
They make a special tool (cable) to reroute a broken cable with a new one that looks a lot like a long cable with a Chinese finger puzzle attachment on the end to grab the new cable and pull it through all the hidden pulleys. Whatever you do DON"T pull out the old broken cable as it's needed to pull the new one through the correct pulley's.
I have all the repair manuals, plus video's of the cable repair I would be happy to share if you send me your email address. The video files are quite large (17MB) so I hope your email can handle the size. The manuals are small enough to send email without issues.
If you're interested let me know.
