I am 100% sure it can handle its enviroment - it is in production, not a crazy prototype.
Problem is likely in what each of us see as off road capability.
For example I don't see this as any crazy trial but just any forest road you can met, when doing some logging (for example).
But I doubt that truck can handle it. Or any other truck from US I've seen so far in game. Same for common road trucks of europe or more eastern places. You need AWD for sure, but AWD on its own is not enough...
On the other hand, it is just my personal opinion, I am not trucker (so far) and don't know a ja****it about US truck production in general. I am just thinking out loud so I can be wrong quite happily
