I figured this out, and am very happy with the solution!

I moved the converter’s positive output from the 12V fuse block to the power in side of the latching relay. I added a length of 4 gauge wire to extend to the latching relay.

This has everything working as I think it should. The Use/Store switch light is on only when the relay is latched - regardless of 120VAC connected or not. When the relay is unlatched the light is off. Also now, when 120VAC is connected, I can use the Use/Store switch to disconnect all 12VDC consumption - yet still have battery charging working. So, whenever I have 120VAC connected the batteries are charging.

I’m not getting any unexpected battery drain, or other issues. My monitor shows what I expected.

The four pics below show my meter (temporary install) monitoring the coach batteries:
Pic 1 is 12VDC only with relay unlatched
Pic 2 is 12VDC only with relay latched and cabin lights on
Pic 3 is 120VAC with relay unlatched (charging working)
Pic 4 is 120VAC with relay latched (charging working)
