I get max of 3 days with 2 house batteries with frig on and lights at night. I use a laptop for 2 hours to show a movie. I still use water and shower (HW via gas).
If I turn the frig electric supply off, I can get 6 to 8 days.
My Dometic RM2852 model frig control boards draw a copule of amps. There is a power disconnect in the freezer door frame so I can easily shut it down and just don't use the frig.
P.S. 1/2 of my internal lights are LEDs and those I use when boondocking.
