Great video, thanks for sharing
This is my backyard and have done the road at least 20 times over the years in several 4x4s, enduro bike, adventure bike, road bike and a hillman hunter.
IMHO - These days I would never attempt to go all the way through in my bus, even during summer as even after they have done maintenance it remains significantly rough in patches and the insides of my bus would resemble a salad tosser after a few of the river crossings if
you could get through.
You could however drive in for some distance from each end without to much drama and the landscapes are worth the effort.
