Air conditioning remains the biggest obstacle to eliminating the standard RV generator like the Onans we are familiar with. If not for that most everything else on many RVs could be powered by large inverter/charger and lithium batteries like Roadtrek is offering as an (expensive) option. Cost needs to come down significantly though.
And once 48-Volt electrical systems arrive, engine driven alternators of 10 kW or higher will be able to charge large-capacity battery banks in minutes. For those like us who mostly drive daily or stay at campgrounds with hookups, regular generators shouldn't be needed.
