I am questioning the advice you are given based on my issue.  

I had a broken cylinder in the front that leaked huge right above the steer tires of the front slide (2 slide coach).  It leaked when I tried to move the aft slide, so there is pressure going to the front slide cylinders when the aft slide is actuated.   I do remember getting a full schematic of the system, and it confirmed this setup was as planned.

I remember there being "t's" that pressurize multiple circuits whenever the pump is on, but dont remember which cylinders they go to.  If you know the hydraulic lines that go to the slide cylinder, I would cap them off at the distribution area (both extend and retract), or in the passenger side front wheel well access point by removing the cover in the wheel well that is underneath the foam spray.  But don't hit the button to pressurize or you will cock your slide........

Just a safety note..... you don't want high pressure hydraulic fluid hitting your skin. If it penetrates you have problems. Wear safety glasses, and use rags around fittings to minimize spray.....

All the fittings you should have to touch are -4 JIC. the -2 lines are for the slide pins.
