Not true, these are two nearly two completely different comparisons. A person who is survival savvy can survive without much of anything. But there is no amount of 4x4 savvy that will prevent you from being stranded in the middle of no where without the proper equipment or spare parts. There is no way around that.
Also, it seems you missed the first part of my response I stated I can look at the show at face-value and find it entertaining .
It's easy to say pull out the right tools and fix it. But we all know that is not the case. Having the equipment is half the struggle. Actually performing the repairs such that it works is another.
