LFP on Shore Power with Inverter/charger?
An inverter/charger requires that you have a battery connected (or some 12v source) so it will supply any 12v to the RV. (Unlike a converter that will do 12v with no battery) Some say not to float...

FWC has shown how temperature changes the LFP voltage so much that you can't really use the voltage/SOC table if I understand him on that. I don't know if you can use a temp/voltage table and allow for the temp so you get "close enough".
The main thing you want to know while camping is whether you need to haul out the gen today or can it wait till tomorrow to do a recharge. You need your SOC now to decide that based on your planned usage between now and tomorrow. Solar is part of that decision of course.
"Close enough" is where the accuracy of the voltage reading matters. An AH counting monitor would be a better guide IMO, with your estimated adjusted for temp, low load, "resting" voltage as a rough cross-check.
