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...

I would never trust the %SOC of a monitor. I do trust the AH count. I don't have the Trimetric set-up to even read %SOC. I do have an idea of the battery bank's AH size as adjusted for temperature. This matters when camping in ambient 35F temps.
I look at the AH countdown from zero and subtract that in my head from my notion of battery bank size in AH to get an idea of SOC. I know my daily usage. Easy to tell if I need to recharge today or if it can wait till tomorrow.
I have the voltage read-out too. I mostly watch that for estimating SOC, which is also easy with "ordinary" batteries. I cross-check the two SOCs to see if they "match". No big deal, no spoiling of quality camping time.
It is easier in the summer with solar, where you can go for weeks without getting down to where you need to haul out the gen. Do have to keep an eye on the weather forecast for overcast predictions. I do watch for when the batts get to "true full" while on solar, and reset the AH counter. If it doesn't get to true full that day, I just leave the AH counter running. ( I have disabled the auto-reset on the Trimetric like they suggest if you are on solar)
If I had LFPs I would not change my ways, except I would miss having the more "accurate" voltage readings.
