Trickle Charging Chassis battery
I am new to everything in our new (used Tiffin 33aa) coach, but am learning fast. I just learned the battery charger is only connected to house batteries, not chassis batteries. I have power connected...

Typically there is a continuous duty solenoid/isolator connecting the 2 banks. It's used for emergency starting and charging the house battery from the alternator - ie the alternator always charges the chassis battery.
Very common for the solenoid to be activated from the ignition. And electronics like the BIRD units can activate the solenoid to provide bye directional charging and disconnect as appropriate to prevent discharge from one bank to the other, so think 12.7V+.
Older units often had a diode based isolator with a different set of issues.
