Batteyr charging in an RV
Here's my rant for the day. I have heard so much outright misinformation, misnomers, and just flat out uninformed individuals passing off their opinions as gospel regarding maintaining their batter...

You might want to read the OP's statement No. 3 again: I THINK what is meant is that RV manufacturers do not wire in the stock converter that they install such that you can switch it off from the main 12 volt circuit but still have it connected only to the RV's battery(ies) so that the converter's function during that time is to only charge the battery bank.
I could be wrong on my interpretation above, but if I'm right .... then statement No. 3 is a true description of what's going on with respect to how converters are installed in most/all Class C motorhomes.
That's how my converter is wired into my Itasca: It can be switched off competely, but of course then neither the RV's 12 volt system nor the batteries see the converter's ~13.6 volts. There is NO WAY to have the converter powered up and supplying ONLY the batteries BUT NOT the 12 volt system. IAW, the converter must be left connected to the main 12 volt system in order for the batteries to see the converters ~13.6 volt output.
However, the converse is not the case: It is possible to have the converter supplying current to only the 12 volt system, BUT NOT supplying current to the batteries (by using the battery bank's ON/OFF connection solenoid).
