My Kwikee system, do not have springs inside the cylinder.
They are controlled by 2 valves, extending / Retracting valves.
Now, my system, will drop when I hit a big bump, however everytime I get out to look, all I see is about a 1/2 drop on one. Fluid is good, no leaks. Yet all I need to do when we stop, extend and retract all. No valves are leaking, cylinder look good. Now I have been living like this for over a year. Until it happens alot. I am living with it. Then I will troubleshoot the system.
Anyway, you are correct until he responds we are in a holding pattern
