thanx for the info. That sounds more to my liking. I was a bit uneasy, because in a Namibia forum the pass was generally rated as very tough - these forum members seem to be all 4WDs though.
My fuel capacity should be sufficient. Under worst conditions I should have a minimum range of 500 k's. The highest consumption up to now ended up with a range of well over 600 k's.
I'll probably take the track to Opuwe to refuel again.
All of the best,
Only when we pause to wonder
