All, thanks for the suggestions. I was able to get it to CW eventually and they got enough pressure in the system to drop the landing gears. The system could not however push all the slides and retract them during our walk through. You could even smell how hot the system was from trying... I have no idea what kind of real damage has been done to that system, and I'm not looking forward to finding out.
I just can't believe there is no way to manually drop the jacks and move slides without major part removal to disengage the slide's locks or get the jacks down to get these trailers off/on a truck. Seems like poor planning since Murphy tends to show up in the worst places!
