Ran out of 12 DC @ 3 AM 1st night.
Our first boon dock night in our new to us MH and the 12V DC went dead. When I bought the coach they told me the batteries were fairly new I need to see if they have dates on them. Now for the use may...

Yes I also would expect 4x GC2 to run the furnace, a few led lights and the tv for the evening and then furnace/CPAP through the night.
Yes test the batteries... probably with a hydrometer first. Few people know how to load test them so most just fail.
The bigger unknown is what else could have been running off the inverter. Possibly the fridge (absorption or compressor?) and possibly the water heater. Most large inverters will idle at 3 amps... then it is the load you connect.
You need a way to monitor battery voltage as a minimum. Possibly consider a full battery monitor.
