Ground Neutral Plug use?

This just came up in another thread, but in their case it was one of the breakers you already found under the bed, so we can rule that out.

Since the last thing you changed was charging the batteries, let's start there. How are you charging the batteries? Did you plug your shore power cord into the Bluetti and now the trailer's built-in converter (Xantrex) is charging the batteries? Or did you connect in some other way? 

Also, to start from basics, are both of your Lithionics batteries currently (no pun intended) turned on (blue light glowing around the power buttons)?

Is EVERY DC item dead? All lights? Bathroom fan? USB outlets? Tongue jack?

*Batteries charged with Bluetti power bank. No problem. Used ground plug and external surge protector. Full charged batteries.

*Have DC abd blue lights on.

*Jack works. No lights.

The "Master Light" switch and all the others except "Curb Awning" and "Rear Camera" would not turn. So no lights anywhere.

It remained that way for 7 hours. Just now it cured itself and all is working! What the heck just happened? Will happen again?

You said the jacks work.  Jacks are fed from load side of the DC panel 60 amp breaker, so it's fine.  The DC fuse panel then feeds a number of things such as the stereo, pump, furnace, refer, ect., and the main switch panel. 

You mentioned the lights don't work, but the awning and camera do.  I have not verified this, but it would make sense that the master switch on the main switch panel only controls the lights including the outside, inside, and closet.  That's to avoid battery drain if you left a light on.  You wouldn't want the camera or awning to be turned off by the master switch, so it's the primary suspect.  

My master switch failed and I had to jiggle and flick it a few times to get the lights on.  Turned out to be a loose spade connector on the back of the switch.  Best to pop the switch out and check it now to avoid an unwanted black out.

Hope that solves the problem.  Geoff

In our 2022 we had a lot of fiberglass dust fouling the internals of the control panel switches. They would intermittently fail. Cycling them a few times would get them working again. I eventually cleared them by using canned air and a shop vac while cycling them. If your master switch is fouled, it would keep all your lights from coming on. Or, it might be a loose connector on the back of the master switch as @Snackchaser suggested.

My guess is also to replace the master switch. On the list when I get home from northern Wisconsin.
