Adam,
Of the four slide locks the seal was blown out on three of them to the point I could not see a failure point.  The last one had not started to leak so being very careful taking it apart I found this seal inside the lock in this condition. 


Finding this condition makes a solid case to use the Double X profile o-ring as stated in my post.  As a side note; they have preformed flawless on our slide locks.

I ordered everything from o ring store and should have today. Biggest issue I have currently is I cannot get the slide back in due to the leak is so bad it cant build pressure. So off to the hydralic store today to get some caps. I am going to cap the lock and unlock hydralic lines off at the pump and hopefully i can get the slide in a bit to tackle this repair. Yesterday we dumped about a quart of fluid out of that slide lock area in a matter of seconds. Luckily it didnt get on the carpet or furniture. I was able to get a small mirror up above that valance piece. it looks like it possibly is held on by 5 or 6 thru bolts. Hoping I can just back those nuts off and pull that large valance off. guess glad this has happened at home and not somewhere in the middle of nowhere

Adam,
I found out when I capped my lock hydraulic lines the lock reed switch could not tell the HWH system what the proper state and sequence the slide's hydraulic system was in.  In my case the floor would not move.  From your post I am reading the slide is out....is that correct?  Even with the leak has the slide locks retracted?  With n the lines off you may be able to manually move the slide pin on the leaking lock being cafreful not to score the slide lock plunger.
