Holiday Rambler electrical issue

[Majorphoebe]

I have a 2002 HR Navigator 45PBT. Today we were enjoying a hot day in MH with AC on. All of a sudden both front and back AC's went off, all ceiling lights, bay electric off. Wall sconce lights work, TV works, microwave, frig, work. Checked breaker and its ok. Shows I have 120 volts in MH, all breakers on. Tripped and reset and still no AC, or ceiling lights.
Very hot here and happened at 6:00, so moved out of the unit.
Anyone have an idea as to what problem may be?
Thanks,

Any display on the AC controller?

ACs require both 12V for the controller and 120V for cooling.

Roof lights run off 12V so I would hazard a guess you have a 12V problem somewhere. Check your inverter breaker(s).
