Hi, I have a 2008 Fleetwood Yuma. I would like to know if it’s better for the batteries Drain to run the CPAP directly off the inverter Alone or to plug the inverter into the power supply for the camper and use the outlets? We love boondocking, but need the power so I wont keep the whole family awake. Lol ive got 2 114 amp hr batteries. My CPAP draws 3.4 amps with humidifier. But I always keep the hunidifier off while camping. Thanks!
