This may be a different problem than you have, but my 2007 Scepter had a slide issue when new and Monaco provided a replacement slide motor. The coach started breaking these shear pins after that at random times. Several times it didn't break the bolt, it sheared the axle off the drive gear. It also started rounding the hole in the square drive tube where the bolts sheared. This went on for a few years with multiple trips to the dealer, independent repair facility and one trip to the Monaco factory in Oregon. When it would shear the gear axle it would require road service to support the slide and reverse the gear to get the slide back in. Finally took it to a facility in Oregon that discovered when the new motor was installed it was larger than the original, causing it to overdrive the slide before turning off, and shearing the bolts or axle. Oregon facility modified control circuits and we haven't had a problem for three of four years now. You might check with Power Gear to see if your motor and controller are compatible. In my case it had Power Gear motor but Monaco designed controller.
