Get rid of the parts replacer and find a technician.
Well stated as he knows little else. Many and I mean MANY RV problems are battery related and should have been the first thing checked. Next would have been does everything else work?
A $10 voltmeter from HF might be a good friend to know.
Power bill: Buy a Kill A Watt and pedestal adapters to determine your rig AC usage. Turn off all rig CB's first then on one at a time and observe usage. Notes: The KAW is limited to about 15A. Turning off the CB's may cause a reset and the problem not be apparent when turned on again. But given your power bill don't blink an eye at the low cost and very helpful equipment.
BTW Did you leave the HW on?
