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...

Hi. BK here, same coach.
You should be able to easily go 1-2 nights on those batteries.
I think your problem was adding a gallon of umm..H2O.
All you can do now is check those 13 year old cables, charge them, check SG, then go buy 4 new batteries (just joking). Seriously, if they sat discharged and/or that low a long time, you probably need new.
I added a Pro Fil watering system as I leave mine plugged in all the time. Makes life easier.
The inverter doesn’t use hardly any amps at low currents; very linear. Easy to monitor when genset is running as it displays AC amps being used. Turn something on and you can see the draw on your EMS panel.
Your batteries are basically under your bed and there is a conduit from the charger to the bed frame so you can easily run a 12V run for your CPap.
Once you have a set of good batteries, monitor your bat voltage with the built in voltmeter and look up a capacity / discharge chart.
