Is there a DC battery charger in my coach?
I understand when I'm hooked up to shore power or the generator is turned on, my battery charger keeps my house batteries topped off using bulk, absorption, float charges until the battery is full. ...

With the standard alternator/regulator, yes, your batteries will be slightly overcharged while driving.
There are (rather expensive) smart regulators that can reduce voltage (goes through the same bulk, absorption and float as a smart charger). Have them on our sailboat. Not sure it would be cost-effective on a motorhome.
Said another way, keeping a fully charged battery at 14 VDC all day while driving is slightly excessive voltage. But cost of cure would exceed any likely damage to the batteries.
