I own an aging 2001 Gulf Stream 33' Class A motorhome that I bought used in 2013. It had "Conquest" decals on it, but the closest owner's manual comparison I have found is for the "Supreme". Anyway, it has the Power Gear hydraulics for two slides and the jacks. Last Christmas, the bedroom slide started "drifting" out while I was cruising down IH 35 south of the Red River. I was able to retract it and "block" it in place for the rest of the trip home. The bedroom slide cylinder checked out and I couldn't find any leaks in the pressure lines, so I assumed the problem was in the pump unit. I installed a seal kit (sold by Lippert who has bought out Power Gear). The problem only got worse, so I have had a hydraulics specialty company working on the problem. They replaced the check valves and thought that the lines were holding pressure again, but they are not. I really need to talk to someone who knows specifically about the Dewald/Power Gear hydraulic system. :confused:
