Dry Camping with CPAP

We are going to be dry camping for 3 nights. My wife has sleep apnea and uses a CPAP with heated humidifer every night. We can't run the generator all night. We have a Rockwood Sig. Ultralite (8315BSS) TT. I would like to have a 12v source for the CPAP in the bedroom. It pulls about 6 DC amps. If I can do this the 2 trailer batteries and the truck batteries can handle the load.
Any help would be appreciated.

If she can tolerate the CPAP without the heated humidifier, you can cut the amps/hour down by a third (usually).

We have same situation, wife uses CPAP. We have not tried it yet but I think two fully charged RV batteries will get through the night but I would recharge next day. You can buy a 12 volt battery pack for CPAP, many sources available, one from our CPAP company is $200, kind of a lot. Amazon has various 12 volt battery packs for less. Please let me know how it works out and what you end up doing. Good luck.

Go to the top of the page and put cpap in the google search box to search
You will find a lot of previous discussion from folks who use CPAP while on battery
Good Luck!
