Is 200 Ah enough?
I have been dry camping with my 2019 Montana with residential refrigerator since day one. I monitor every night's use with my victron fuel gauge as I call it. It records every amp hour in or out of the batteries. On normal overnight stays I use approximately 100 amp hours running the refrigerator. I use an additional 100 amp hours on a cold night where I have to run the furnace. So for your instance if you have 200 amp hours of lithium which you can use about 80% of that you will be good for one night and a little bit left over. What you want to explore is to put some solar on your roof. I will be at quartzite this year and I'll probably bring some solar panels along with me. I have eight of them on my roof, you can find these all around the Phoenix area for $25 each for $185 watt panels.
