Longer term, I have little doubt that to electrify van and or motorhome chassis to serve for RV applications more effectively, that the electrical system (alternator) must be upgraded to at least 48-Volts in order to better power air conditioners, microwaves, etc. It’s all moving in that direction but not fast enough for my taste. Many companies are holding on to 12-Volt systems because it’s presently more common and cheaper, but 48V is slowly being adopted.
I recently read that the common aftermarket second alternator supplier plans to release a 48V alternator kit. Between that and 48V (nominal) batteries, we should see faster adoption of 48V in lieu of 12V.

All that really means is a ton more posts on here about "how many 6-V or 12-V and in series or parallel do I need to get my 48V system right??"
