I remember watching a Big Time video on Youtube about what one needs to have on hand just for a track day when testing a rebuilt drift car. There was quite an array of tools and parts, plus water, food, and first aid. And that's with help close to hand and good cell signal. Going into the wilderness is not to be taken lightly, and around here, people take Jeeps straight from the showroom to the woods and get themselves in big trouble every summer.
Yep, I get it and so many people do what you said, take stock vehicles out to places they should not and without any skills whatsoever. They're the ones that come to grief usually, cause damage to the environment and themselves. Not smart.
