I have 2 mutally exclusive conditions I need to satisfy:
1) keep the fridge running when parked (not camping) - I need a 12v source for this even when running off 120VAC
2) ideally keep LIFePO4 at 50-80 SOC when idle for extended period. This means I don't want my charger topping them off
The Samlex will not provide 12V on it's own (my current Boondocker does as converter), so if I activate the battery cut-off, I do not satisfy condition 1).
One option Samlex suggested is to keep the Samlex on in 2 stage charging mode, let the batteries draw down on parasitic load and then trigger charging when the low threshold voltage is met (I could set that at 50% or 12.2V.
Other option is when arriving home, turn off Samlex completely, set battery cut-off to 'off' and plug shore power directly into the Boondocker to provide 12V and 120VAC to RV for fridge.

I need a separate source of 12V to the RV while batteries are off to keep appliances going.
I'm not following this part.

I contacted them about their spelling.
