Hello to all of you. I am going on a 2-3 day snowmobile trip to the UP in early Febuary with my riding buddies. I use a CPAP machine to sleep, 20 or so years now. I am not worried amount transporting it as I ride a 2017 Pantera 7000 LTD. Storage is ample. My concern is that any residual moisture in the machine from the night before might freeze in it and cause problems. Two things I thought about to prevent this are packing those hot hands packets in the carrying case or put the machine in one of those 12v heated lunch bag things and plug it in to my passenger 12v plug in outlet. I would like to hear what other people who use a CPAP machine do when you go on over night trips while out on your sleds.
