Jim, many of the suggestions offered here will help you enjoy the outdoors. As a CPAP user, I highly suggest using a power source that will allow you to be overlanding for several days. I currently use a Goal Zero 1000 and charge it with 200 watt solar panels. However, it has its limitations particularly if it is raining, or cloudy days, etc. Is this setup expensive? Yes ! There are other suggestions mentioned in this post that may work just as well. Your choice! The bottomline is, there is nothing like a good night sleep regardless of where you are. Best of luck.
