I don’t know if you have 4-wheel drive on your Russian oxcarts but, no, over here we don’t have to stay on the roads.
LOL. I know everything about 4-wheel drive, 6 and 8-wheel drive, low ground pressure off-roaders, amphibians and I’m licensed to operate and have access to tracked all-terrain vehicles too.
I owned 4-wheel drives since my second car (or third counting my father’s hand down) in late teens.
I also traveled to places with a humanitarian crisis going on with collapse of infrastructure and civic order so I am somehow qualified to share first hand experience.
I assure you that unless you are living deep in the rural area, your big @$$ vehicle would be the first thing you wouldn’t be able to use in case of any major crisis.
The roads would be packed and jammed and what kind of off-road terrain you are planning to traverse in urban or suburban environment? There are indeed either road or structures and you ‘ll need no less than medium tank to go through the latter.
Another question is where do you want to travel off-road since every place of human interest is actually interconnected with one another with roads anyway.
Even if there is such a place what would be your gas mileage off road? Would it be sufficient to reach anywhere?
And you won’t be able to use it in rural area as well, the moment you ‘ll need to refuel but there won’t be gas on your nearest station.
I am here not talking against big trucks which are valuable things for many situations.
I am actually questioning unrealistic prepping strategies build around vehicles like that.
I actually believe you better look at scooters as you doomsday vehicle of choice no matter how unorthodox and silly it sounds at first glance.
It is quite a long to explain but I can try if you are really interested.
