Will be replacing my dead Norcold N821 with a 9.8 cu ft residential in 2 weeks. Refrige draws 6.0amps/690 watts on start and 2.5amps/287.5 watts running. Planning on a 1200 watt PSW inverter which will handle load . Question is how much battery do I need?

Currently have 2 automotive batteries, not sure of size. That was my question, what size (amp- hour) would I need.Undrstand the 2.5 amps per hour, but refrige doesn't run continuously.
As long as you limit your off-grid usage you should be fine as is with two batteries and 1200w psw. You can still stop for lunch and take your time at some tourist spot to explore enroute.
If you plan to overnight without utility power you will be pushing the pair pretty hard if no generator use. I would go 4x golf car batteries. If going extended camping off-grid I would be at 6x battery and 600+ watts solar... Maybe lithium battery.
