I mean, I have been driving for the last 30 years of my life, I've driven most of the north east of the US. Through highways, timber roads that are little better than muddy paths, country roads that have never been paved, and pretty much everything in between. I've driven 15 hours straight. I've driven up mountains and across (really small) rivers.

Between all the vehicles I've driven in my life I've accrued, got I hate that I know this number off the top of my head, around 350k miles.

So yeah, I do have experience with such roads.
