Hi. Went to the dealers who were working on my 2003 Travel Supreme DSO4 to hopefully solve a leveling/air system issue. Noticed my coach generator was running. The door was locked, the main power switch at the entrance was off, no key in the ignition. Asked the service manager why it was running. He had a puzzled look & said it was not running when he arrived at 7 am This was now around 10:30sh am. He said he noticed that it was running and did not know why. His rv mechanic was out sick. He said no one else is working on or in the coach, and the key was at his desk in the office. May be an AGS system but I don't have the documentation to determine if so. Any ideas? Thanks
