Hi! I have a 2021 Fleetwood Flair 28A. The leveling system seems to not recognize that the parking brake is engaged.

I park, engage the parking brake and then hit Auto to level. This is still working most of the time, but occasionally, the levelers auto-retract and show an error that the parking brake is not engaged.

When I do get the levelers down, I camp normally. As I'm cleaning up, when I start up the engine to begin retracting the levelers and slides, the levelers just start retracting on their own with a beeping noise on the controller indicating parking brake. 

I'm taking the coach to General RV for service, but would appreciate tips/guidance to give to the technicians.

Looking forward to your thoughts!
