Question on switching to LiFePO4 batteries.
I'm going to replace my 2 lead acid batteries in my Bigfoot truck camper with two 100ah LiFePO4 batteries. I've previously installed a 4 way battery selector switch to allow me to keep one of my batt...

A common shunt size is 500a, but they also come in larger sizes depending on whatever
your needs…Also, some manufacturers SOC panel meters use a proprietary meter connector, so if you plan on a particular meter later on, get the shunt that’s compatible, or simply choose a shunt with a Bluetooth feature.
As to your second question, yes one battery will try to charge the other battery, so IMO best to keep them in a parallel config…
Upon edit, I would also add that if one battery were to charge another, the shunt meter would not measure this activity, which will result in unwanted inaccuracy, and in a similar sense, trying to determine SOC of an LFP battery by measuring voltage alone is impractical, only slightly better than a WAG (wild arse guess)…LFP’s are not cheap, and they deserve proper care…
