I benefitted from a similar thread a few years ago. We had a new to us motorhome and it seemed like the batteries fully recharged from an hour or two of driving because the voltage went up to 12.6 a couple of hours after charging.

A $25 eBay battery monitor made it possible to monitor the state of charge fairly accurately and just 100 watts of solar in addition to the engine charging keeps us going pretty well indefinitely in summer. Just fridge and LED lights.
