If I was in your shoes, I would close all valves.
Open the first valve and begin extending the slides - only one should move. When it begins, stop the motor by releasing the switch. Mark this valve with a Sharpee. Close this valve and repeat for all remaining valves.
You'd be best to have a helper who can watch one side of the RV for movement while you watch the other.
Even tho it's stored indoors, no slide should move fast enough for you to do this. You don't have to fully extend it. Just enough to know which one is moving.
