Jack,
Your slide/leveling pump and reservoir is probably located in the RR of your coach just inboard and forward of the battery bay. Most Patriots used this location instead of under the front steps like the Marquis.
Mike,
In the SMC era of Beaver production, most of the slides were HWH, and since there was an HWH pump and reservoir to operate the slide, they hooked the leveling jacks to the same pump. However, when Monaco built your coach, they used a complete HWH slide system including the pump, and then installed a Power Gear hydraulic leveling system including another pump, which in my opinion is a waste of space, weight, and money since the HWH pump could have operated both systems equally as well as the version that was installed.
