So you're saying "smart" vehicle charging systems are not capable of handling large or small accessory electrical loads like a snowplow, ambulance needs, camper battery charging, winch, etc?
There is a big difference between the load placed on the charging system and starting battery from a snowplow or winch and that of a camper battery.
Electric motors will still run, although slower, when the voltage is below 12V.
You need AT LEAST 13.8V at the camper battery in order to REPLACE any energy !! At 13.8V at the camper battery, it will be impossible to get ANY auxiliary battery bank up to 100% state-of-charge.

Ask all the dudes with new trucks and dedicated accessory charging/loads that are/were installed after the truck left the assembly line.
I was an automotive engineer for one of the Detroit 3 for over 30 years. While I did not personally develop the charging algorithms, I know the people who did. These algorithms have gotten more sophisticated in the past 10, including "state-of-charge" sensors and/or true current sensors.
The goal of these charging algorithms is to replace the energy consumed from starting the engine AND to not allow the battery voltage to drop below 13.2V-13.8V.
EDIT : I forgot to mention, yes the algorithms are modified when there are TWO batteries installed at the factory !
