Log,
Voltage may be the least accurate method to check state of charge. I suggest verifying the charge level a few times using a temperature compensated hydrometer. You may be surprised at of "real" state of charge where the battery charger goes into float mode.
I believe voltage is close enough for this discussion
The issue here is whether or not a motorhome with a "smart" charging system fully charges the batteries with the engine alternator. And if they require a DC to DC battery charger as advocated by you and THEOLDWIZARD1.
The answer is they obviously don't.
The fact that your highly modified motorhome may require one in no way shows that the average motorhome requires one.
After a day of driving, even if the batteries were slightly lower than fully charged, shore power or generator would almost immediately restore them to fully charge (measured by any method).
This high tech talk you are exposes means nothing to the regular motorhome owner. And, the suggestion that they should add an expensive, unnecessary piece of equipment as a DC to DC battery charger is ill advised.
