WE have an '05 42' PT Richmond with 4 slides, Cat C-13 525 hp.  The coach has only air leveling. This is a new coach to me so am still figuring out how things work and where they are.
The bedroom slide has begun to creep in a few inches within a couple of hours.  All the other slides are working perfectly.  Is this slide operated via electric, air or hydraulic?  Have read several threads about slide creep.  But before I start taking things apart to investigate want to gather as much info as I can.  Also, I think I have a hydraulic pump near the entry stairwell.  How do I gain access to the pump and reservoir?
Appreciate all the help!
