To give a bit more information. It's a 2017 Keystone Bullet 247BHSWE. Batteries are two Pape' material handling deep cycle batteries. Model no 24DC75. In the A.H. Capacity it says "75 (20HR)."
The refrigerator is a Dometic DM2652 that I had set in the Auto position. Maybe I should have had it set completely on gas...
We had the water heater purely on propane.
We did use the water pump, though we were fairly sparing in our use of water.
Didn't run anything at night, though my wife was up a few times to feed baby, so she would have used the light.
Sounds like I should just resign myself to not dry-camping unless I get a generator or solar.
