Bounder: AGM and wet cell charging

[moisheh]

I am considering a 2005 Bounder Diesel. It has 4 AGM,s and the 2 wet cell group 31. I have not seen it yet. It does have a xantrex factory inverter
How does the charger handle the 2 different types of batteries?

It doesn't. The charger, in your case inverter/charger, charges the house batteries.

There is a separate device, possibly a BIRD ( Bi-directional Isolation Relay with Delay )
that handles battery to battery isolstion and charging.

AGM and flooded battery charging parameters are close enough that one setting is fine.

As twinboat says, the inverter/charger doesn't even know there are extra batteries. A "battery charge controller" device (BIRD or similar) connects the chassis batteries to the house batteries when and if the chassis needs charging. The inverter doesn't know, so uses whatever charge profile it was set for (presumably the house AGM setting).

How will the equalizing mode affect the different batteries with a set up like this ?

[twinboat]

Should be fine since you don't equalize AGM batteries.
