[Problem Solved] A/C and ceiling fans not working....

Glad you got it figured out.

Good deal and you became a little bit more skilled with a meter and a lot more knowledgeable about your DC system. Definitely a "W" (and probably faster than an All Star game).

Congratulations! Roundabout, but it's a "W"

It would be nice if, in the schematics somewhere, they noted the position of this "switch"

Well, don't I feel dumb. Spent 3 hours contorted in the basement, raining outside so I'm working in the area the size of a large suicase, banging my head...knew the two black wires had taken a detour and knew there was a switch down the other side somewhere, then I saw two heading up by the side of the basement hatch door. Aighhhhh...I knew there was a knob there but I thought it controlled the shore power not the 12V. Probably should have JUST CHECKED IT ANYWAY. Got popped in by something. Pulled it out....annnnd there you go. BUT, one day down the line one of those breakers is going to go and I'll know where they are and how to test them. Thanks to you guy. I also found my water pump which by some miracle is still operating 14 years later. Now that I have everything opened up I'm going to do a thorough inspection in the morning when it's dryer, look for leaks....

Now I'm *really* glad I tried to trouble-shoot this myself because I really would have been ticked off at myself if I hired someone to come out and pull a knob out 1/4 inch. What's the point of a switch like that? Does it preserve your batteries during storage? The last time this happened the jacks wouldn't work -- that's probably why I didn't think that was the problem this time, but maybe I was unplugged from shore power this time

Anyway...thank you...very very much. If you find this thread, have lost your 12V power, look inside the hold for a knob with a little sticker that says, "Interior Power"

I will never make this mistake again.

I just tested the entire main panel and subpanel. Everything there is a-ok. (I'm getting the hang of this.) Those wires are bundled so tightly and there's nothing lumpy anywhere heading all the way up to the fuse panel. I cannot fathom where that thing is. If I have to unbundle all the wires bit by bit to find it, I will. Grrr...

Thanks for your help. :)

Actually, I was wrong.

Chris stated the DCV cutoff switch could be the problem and he is probably correct - I just looked at the schematic. I am not sure where it is located in your camper, but it will disconnect 12 VDC power to the loads you are concerned with.

Trace the Black, 8 AWG wire on the silver post back to the switch connection.

The switch is located between the breaker connection and fuse panel.

So it might be the AC breaker, even though turning that off and back on again doesn't do anything? This wouldn't explain why the slides and the 12v lights don't work. ?

No, your AC side is not working, but your DC is.

Since you are not familiar with measuring voltage, you should find some help to troubleshoot the AC side.

Your schematic shows a main AC panel and a sub panel. The main panel supplies voltage to some of your AC loads and the sub panel. You need to have someone check these voltages for you at these panels.

AC voltage is much more dangerous than 12 VDC, so tread lightly...
