Hydraulic slides slipping out while driving

[MattM]

I tried putting a broom stick between the coach wall and slide but the pressure started to push out the fascia board on the inner wall of slide. Not much else there to grab.

Here's the latest: J&L Rv repair replaced two hydraulic rams they said were leaking at $1,000. Did not fix it. Then they said too busy, come back in 3 months. Got a reputable mobile tech, he tested rams, found another leak, replaced it with LCI's new aluminum ram that does not work with the older rams (diff flow rates), had to get a second one replaced yesterday. So main slide has two new aluminum rams for $1,300. And got up today and saw that the opposite slide out had moved out 3-4 inches during the night. Unbelievably frustrating.
