Both the Dealer and Keystone should know there is NO manual crank on the hyd slide out system.
You have got to refill reservoir to be able to close the hyd slideouts. Either AW32 or transmission fluid depending on what you had in the system.
Here is your main concern... with a leaking retract line or fitting you will gradually LOOSE hyd pressure on the slideout that is leaking
That is why your slideout was extended at the bottom when you arrived at last destination.... there was no hyd pressure on retract side to hold it closed.
