I had my first real failure on the trailer
The front slide out in the bedroom refused to extend. Only one side would move out a couple inches and it would stop. After a little on-line research I found that the front slide is a Lippert/Schwintek in wall slide out:
Schwintek In Wall Slide-Out
The unit controller is installed in the front storage compartment and would fault when only one slide would fail to move.
I took the trailer to my local dealer and they contacted KZ for warranty repairs. It ends up there is a common fault with the motor units and Lippert covered replacing both electric motors in my trailer under their warranty. I'm glad they replaced both motors so I hopefully won't have further problems after the warranty period ends.
Thank you Lippert making my problem right
