Most have not experienced that for sure, even when I was in the army we had power all the time (signal corp), but not for heating - minus 40 C/F is interesting haha…
Living in old boats & vans in the summer was great though, but would not like to do so in the tropics!
Cold is easier to deal with off grid as long as you’ve got wood, oil or coal to burn of course. Rain and dampness on the other hand can be hell even in tempered climates…
Reminds me of when a business partner of mine bought a genset for his web dev guy in Kathmandu haha, it worked somehow, was in the years when you could do dev work offline :-)
