48V auto electrical systems for mild hybrid is already a reality. We don’t need to speculate.

Yes, they use a DC-DC converter to step down a small amount of power from 48V to 12V (nominal) for items in vehicle which are already there, like lights, radio, power windows, windshield washer, etc.

It is expected that as new vehicles are designed with 48V electrical from the onset, many or all of these items will run on 48 Volts, so there should be no need for DC to DC converter.

The RV industry will likely follow a similar transformation in my opinion. Initially the use of 48V will be extremely limited, but it should become a new standard in time. Just my guess though.
