It could also depend on who installed it and how it was wired. On our '82 the entire Switch Panel was Hot!
I was doing some electrical work just after we purhased the coach and with diligence I checked the panel to ensure that it was off and it wasn't!?!? surely surprised me. I disconnected the shore power cord and still reading voltage!?!? After tracing down the wiring I found that the Inverter was wired using the relay to power the entire switch panel.
I installed a Manual Source Isolation Switch (Shore and Generator came from Newell with the Relay type Source Isolation) and gave it a dedicated Circuit. My HEART Inverter now only powers the TV in the Bedroom, the TV and one Outlet in the Saloon (Living Room) and the Microwave Oven.
A small plug in AC Outlet Tester is very helpful and if you get the one that tests the Ground Fault Function you would also be able to prove/disprove those Receptacles.
Good luck.
