For your request, quigley site have/had demo video of their van in Moab and where climbing some rocks.
Regarding my overland travel definition here in the US it is using back-country road / trails where conditions might not be smooth and graded.

Overland Journal is a publication about Overlanding:
I'd be interested in hearing how others define Overlanding.
Now your quote from the link is true in some foreign coutries where nature cleans out the trails.
For example the Sahara in Africa, driving thru the sand dunes and after 5 minutes wind you have no trace again...
But as already mentioned when you travel long distances with your home on wheels, do you really want to push it to the limit of being stuck, broken down or prefer to enjoy the trip by sometimes going around the hard part...
