Once we know what rig you have, more help.
Sounds without that info, you have blown a main battery fuse.
Yes it does, if everything works on generator or aux boost.
Presume that aux boost connects the house panel to the start battery. Likely bypassing the blown fuse or breaker.
Live short of the +house battery guaranteed blew the fuse or breaker between the battery and the house panel. That would keep 12V loads from working off the house batteries.
Cameras ( plural?) may be wired to the house?
Not sure how that translates to the parking brake light, presuming that is part of the chassis system and not the house?
