I'm having power issues that I don't understand. This spring the battery for the engine was dead even though the RV was plugged into shore power all winter. It wouldn't keep a charge so I replaced it...
REfrig, A/C ,Water heater, etc. need 12 volt to work the control boards even when using 120 volt shore power. Check to make sure you have a 3 stage converter for charging the house batt. if you don't and leave it plugged in all the time your just boiling the water out os the batt.s. You are checking the batt. water level at least once a mo. right.
