After years of trying to keep my wife warm camping and throwing crazy money at high end sleeping bags, insulated sleeping pads, etc I am going full cheat codes.
My wife sleeps colder than any human I have ever known, she is claustrophobic so a mummy bag is just right out, and we have a couple high end down filled 2 person bags (Big Agnes King Solomon 15 and Sierra Design Backcountry Bed 20 Duo) but even trying to tuck myself or our son in with her for body heat she just moves around so much she ends up halfway out of the bag and wakes up freezing... over and over again.
Sooo I am certainly not going to throw in the towel on camping, but also don't want a miserable sleep deprived popsicle of a wife so I'm going big battery bank, inverter and a full residential heated mattress pad, if that's not enough I'll throw a heated blanket on top of her too and just roast her to her hearts content
We did over a year of full time travel in an RV (Grand Design 399TH) and I'm just over it. I don't want another camper, not for a long time. I like that I can keep all of our camping gear sans food up in the cargo box full time and we can go on a whim. I just need to solve the comfort factor for the wife and this seems like a pretty fool proof solution. After building the off-grid energy system for our RV that would run 3 AC units off grid in perpetuity I feel like I have a pretty good handle on how to design a solid system for this use and I'm sure we'll find other creative uses for it as well.
