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. ...

Sorry but I guess we'll have to agree to disagree.
The factory alt will not over charge them. At 14V and a fully charged battery there is virtually no current to the battery and it can take it because there is constant electrical activety. Another note is that they are usually temperature compensated by the vehicles computer so voltage is kept at a max safe level but lowered at elevated temps.
This whole concept is evidenced by our vehicle batterys lasting upwards of ten years or more in many applications. If there was an issue of over charging then they wouldn't last that long and manufacturers wouldn't build charge systems that way.
