another place where there's a lot of overlap is bbq, real bbq, cooking over live wood fire which takes a lot of the same impetus as owning/driving/working on a TJ. To cook outdoors over fire you've got to be willing to get dirty, spend more time doing it, spend more money, pay a little more attention to what you're doing, be less comfortable, have much bigger messes to clean up
, subject yourself to all variety of weather, and generally lean more towards the art of creating something rather than pushing a button (either on your phone or your microwave) to end up with some highly choreographed and predictable plate of food or driving experience.
I was immersed in the bbq world for many many years & the folks tend to be as you described, generally happier & much less with the stick up the ass you'll see in other areas.
