That would be dependent on if the house and chassis DC power buses have the capability of being cross connected to support the charging of both. Most rigs, but not all, are set up from the builder to do so.
What is the make, model and year of the coach the Magnum MS2000 is installed in?

Skip,
As it was built, most likely it does not do that.
In the 20 years since that coach left the manufacturer, a lot may have transpired. While a piece of the system may have been replaced, or a device added, most likely this does not been done. It requires the owner to put in that capability.
Without knowing that specific coach, I can only make a guess and recommend a device called a Trikl-Start. That will charge the chassis battery when connected to shore power. Or, if the isolator that allows the house battery to be charged by the main engine (chassis) system has been replaced with a "Combiner", then that is taken care of.

Doubt your 02 CCC charges the engine batteries.
This post is my opinion (free advice). It is not intended to influence anyone's judgment nor do I advocate anyone do what I propose.

Put your voltmeter on the chassis battery after a few days of resting while plugged in.
13.2+ volts indicates charging. 12.6 or lower indicates not charging.

Best answer, as it neither assumes how it was originally wired, what was modified in the 20 years since leaving the factory OR what no longer works.

Ours does. It came with an isolation relay from Monaco for that purpose.

If testing shows no charging, add a Trik-L-Start.

Typically, coaches have a relay which closes a circuit when the engine is on that allows the vehicle alternator to trickle charge the house batteries. Once the vehicle is turned off, that relay opens and the vehicle electrical system is isolated from the house electrical system. In this structure you'll have an emergency start or auxiliary start button on your dash. That button closes a relay which allows the vehicle to start from your house batteries. The idea is that if you have been parked for some time, maybe you have had shore power or maybe you have run your generator, but your house batteries are full, you can start your rig with house batteries and get going. This is the historical way most coach builders have provided for any interconnection between house electrical and engine electrical. Ideally you want the two systems to be separate from each other.
Unless a previous owner has modified this electrical structure, you should assume that your chassis battery is not connected to the house charging system except for the situations I detailed above. The Trick-L-Start would resolve this limitation for you.
