Boondocking with a CPAP machine

My wife has just received her first CPAP machine so I have a question. We like to boondock. I am thinking of adding a separate battery just for a small inverter to run her CPAP machine. I am thinking of using a battery isolator so that the RV converter, and tow vehicle can charge the seond battery, but nothing from the RV could draw from it EXCEPT the CPAP inverter. Anyone here wire an isolator in for two batteries? Or any other ideas to help settle the wife's fear of the battery draining while using the heater and such in the coach??

I have know two different couples over the years that used a cpap machine.
Both were able to continue to camp happily, and successfully with the aid of a small Honda generator.
Which also eliminated the fear of the battery problem.

What are the specs on the CPAP machine? How many ways to run it?

My Wife uses one. We added a 12v outlet right next to the 110v outlet on her side of the bed on our Crossroads. When we somethings stay at a location without power, we just plug a 400 watt inverter into the 12v outlet and her cpap into that. Works just fine.

I forgot about it. I did wire in a set up on an older ford truck I had. We use to go to Canada a couple times a year fishing. I was afraid we would kill the battery running lights sitting there at the lake shore and not be able to get the truck started when we got ready to come home. I don't remember how I did it, but I don't think it was to complicated.
You should be able to pick up what you need for the job at just about any auto parts store. Just explain to them what you are trying to do and they should be able to get you the parts.

The battery/inverter setup would be OK if a person wasn't going to be sitting in one spot for very long.

Personally I would go the Honda route.
That way you got something to charge the batteries when ever needed. Especially if you have to run your furnace very much.

After spending a few thousand on a camper, I think the price of a Honda is pretty minimal. Especially for what it would be used for.

This would be a good option.

yes I do agree that a Honda would be used for more then just the cpap. But I am thinking they want to do something a little cheaper and something can be hooked up inside the RV for them to plug into. Just my opinion..
