Auto Transfer switch mystery for 2005 gulf stream

[Rvcamphunt]

Hello everyone Im new here. I am having a hard time locating the transfer switch for a 2005 gulf stream Conquest Ultra Super model 6331BK.
I looked everywhere and no luck Im almost wondering if it was pulled out. I looked under the bed, behind cabinets, behind panel, restroom sink drain, under dinette, behind couch, under coach, u name it I just need someone that has the similar coach to tell me. One place I heard but not sure that it might be under the steps but it looks like its not the case but any help helps. I get a humming sound from the generator when plugged into the shore power so I figured it might be the switch bad.

Please help. Tried calling Gulf stream left messages and nothing.
