#1 In 24 hours, hmm not sure, never timed it that far. In the summer, typically I use 160 amp hours between 9pm when I shut down generators and noon the next day, when I usually leave the trailer to explore locally. That's leaving the microwave clock on, fridge on propane, usually a few hours of TV for a movie or running the radio, maybe some microwave popcorn and always 1 or more smallish AC fans running.
#2 I have four batteries, #3 200aH, #4 4x group 31 AGM parallel at 12v, #5 see #1
#6 I now have dual generators, twin Yam 2000iS, I usually start them around 4-5pm and they run flat out until 7, that'll take me from 70% SOC to 95%, then I switch one to ECO and the other OFF to finish that last 5%
#7 The furnace is a big drain... boondocking in the winter I use 30% SOC or more over night, with the furnace running more or less constantly, plus more lights on, even though LED, they add up. Plus cold batteries are a lot less efficient.
