Refrigerator draw on LP mode
I'm evaluating my total amp draw in order to properly size a new solar system with lifepo4 batteries and all that entails. My Fridge is a Norcold N821 2-way. The decal inside says it draws .8 amp...

That spec is likely the maximum and not the aveage. You could use a ammeter to measure amps at different times like ignition, cooling, etc.
The easiest and most accurate way to do an energy audit is to use a battery monitor and even $30 ones will provide accumulated power usage for a hour, day, etc. I use one for another application that gives me Wh and I divide by 12.4 to get Ah.
However my first step was a $160 battery monitor and I made a list of amp usage for everything in the rig, turn it on and note the amp change and voltage (charger off). It has many parameters like SOC, usage per day, etc.
Recommend a good battery monitor.
