Jerry, did you get your slide issue resolved?
The reason I ask is my coach began doing the same thing, driver's side front slide inching out as I drive.
There was a hydraulic leak from the slide cylinder. I had the cylinder reworked. The cylinder no longer leaks. But now the slide creeps out while I drive.
The tech, having worked on the cylinder, is aware of the hose connection to the slide cylinder.
Curious if you found the solenoid/manifold to the slide cylinder. Did you replace your hydraulic line?
Thanks!
Paul
