Question HWH Hydralic System and Cat C-7 Alternator

Just a bit of info for you guys with HWH hydraulic systems. I travel north often in early winter and therefore run into a lot of road salt. since I'm on the road approximately 2 wks at a time I pick up a lot of corrosion since it's very difficult to clean salt off under carriage will traveling.

While in ME a couple of wks before X-mas the bed room slide got stuck in the out position. Temperatures were in the single digits and I thought maybe I had some moisture in hydraulic system. So i attempted to open the 1/4 inch nut screws on the solenoid piston and in doing so rounded the sucker. It's appears to be brass so with the extra corrosion - oops. Luckily the slide did come in later in day after playing in the control compartment under front stair. At that time reason for the working action was not known. Slide stayed in rest of trip.

After returning home I tried it again and yep got stuck in out position. The hydraulics are not easy to work on. The home is a Winnebago Journey 2007. Hydraulic unit located under top stair and wedged between frame and stair case. From top there are 4 large pistons on top for leveling on front, a series of hoses going into hydraulic header, 3 up x 4 across on back side and the slide pistons located 2 on back under hoses, 2 on front under larger pistons. Hard to get to the small slide pistons. At this time, knowing the front small piston nut screw was rounded, caution was used to screw "counter clock wise" the nut on the retract bedroom piston. No such luck, it also rounded. Impossible to get to. Started to check electrical, all good, plugs difficult to get to though, turns out a little corrosion in plug to retract connector. Though difficult to get to, easy fix.

CAT C-7 alternator also loose resulting in low voltage across chassis batteries which also added to stuck slide. Alternator comes loose after traveling in sub freezing weather (?? ) even though it is torqued to correct ft/lbs. Doesn't came loose unless it is be below 32 F.
