I do have a generator which I use on rare occasions for the A/C or to give the batteries a charge if they drop down to about 50 percent.
When we planned for RV living, we exchanged my wife's CPAP for a 12v model. I don't mean using an inverter but a true 12v CPAP. It still draws about 3 amps if the humidifier heater is in use. She manages with the heater turned off or on a very low setting by first heating the water and then wrapping up the unit to keep it warm. She has even used a hot water bottle to keep it warm.
