Hello everyone,
Thank you for even more information. The RV has and is plugged in (inside a storage unit, 50-amp).
What I seem to be hearing you say is that the house batteries might be fine (because they were being kept charged by being plugged in), but not the chassis. Thus the chassis battery could have died just because of the time it sat.
I can test the batteries with a Voltometer and the chassis battery can be kept up trik-l-start unit.
Also that even though plugged in, the CO meter and other things continue to need about 35 amps a day, which is (probably) drawing from both chassis and coach batteries. Which means the chassis battery can die even if plugged in.
I will get a voltometer and check both house and chassis batteries. If all checks out, the. I will try to find out what is wrong with car seat, radio, and turn signals.

I can't believe it is so fun to learn about something so complicated!
