I'm still learning.
I'm always still learning..I have read and read about this and came up with what works for me so far.I don't use the humidifier,I set it at 0, when in the hills without AC.I don't notice any issue doing that but do at home..I guess it's all in the humidity where your at?I always keep the reservoir full even though it is set at 0.So far so good,I keep waking up.
A portable C-Pap with battery pack large enough for 8 hrs of use cost more than a good used Lance camper.Not in my budget.With a Honda Gen and a couple newer group 27 stand alone batteries I take with me for the extra 12 volt stuff for over and above the unit needs works well with a travel trailer but I'm selling the pickup for a 1 Ton of some sort to get back into pickup camping instead where carrying extra batteries is not as easy without a trailer in tow.
I'm all ears to what works best in a pickup camper.With my ATV trailer in tow I see no issues but without..Hummm..Except a good charge every day...
Lots of people using C-Paps without electricity and there is know substitute for there experiences doing so,so I'm listening and learning.:B
