I have a 3000 watt house inverter and a 1000 watt invert for the residential refrigerator only.

We parked at 5 pm and powered up the residential inverter for sat tv and relaxing time. No microwave or Air Conditioner/heat pump.

We went to bed at 10 pm so I turned off they house inverter. We have the furnace on and I use a CPAP off 12 volts.

You can see that we use 290 amp hours from t pm to 7:30 am. I estimate 400 amp hours in 24 hours.

The half hour reading was making two cups of coffee.

I use a victron battery monitor reading current draw.

I hope this helps you analyze what you might need.

Safe travel and have a Blessed Day.
