Hi, I see no responses to you so far..... so just as a start.......perhaps someone shut off the use/store switch when you were camping and the coach batteries discharged, even while you were connected to shore power? What is your coach battery voltage unloaded (fully charged or not?). The inverter coach battery feeder fuse sounds like it is good from your description......does the inverter indicate its actual input DC voltage and if not, can you measure it at the inverter with a voltmeter?
