We now have the technology to have quiet 110 volt power available. nverters and solar technology are game changers. Inverters will eventually become optional if not standard equipment on all campers.
Residential refrigerators are now common place and just the start of inverter technology in a RV
We have not found an easy way to run A/C yet but microwaves and most appliances are usable via inverter.
THere is a learning curve to keeping batteries charged but at the end of the day quiet 110 power is available for RV use without totally breaking the bank.
Being locked into 12 volts is just old school thinking.
Inverters have arrived.
