We have 4 12V batteries in our Hurricane and 400W of solar on the roof. We dry camp fairly often but not for long (more than 3 days) periods at a time. We have found the batteries hold up with the combination of alternator, solar and maybe a couple of hours of generator charging (if it is cloudy or rainy) and this includes the residential fridge, TVs, satellite and gaming systems.
Of course, there are limits and everyone must be conscientious about turning things off when not needed or being used.
