Orbost to Delegate with van C612

I did it about a year ago in the opposite direction towing a Karavan. A friend did it more recently in your proposed direction towing an Avan Cruiseliner. I.e. both were compact and not heavy traliers, both towed with late model Prados. We both concluded that it's something you only do once. It's doable, the road is in good condition and not too narrow and the route is scenic, but it's very long and very very winding and thus very very tiring. Going uphill may be easier as there's less braking, although my friend still came to the same conclusion. The road often has a lot of forest litter, and there are occasional logging trucks.

I found the short 2km bit just outside Delegate heading North-South was the worst. There's one bit that's downhill, corrugated, off camber and generally horrible. I did it twice in 3 weeks and both times I thought I was gonna stack. The second time I was ready for it, had a lighter bike, better rubber and it still bleep ed me up.

The 11km bit in the middle is easier but still fairly shit. I was managing about 40-50kmh through it. If they ever seal those sections then it'll be possibly the best stretch of motorcycle road in Australia. The fun of all the good bits more than outweighs the suffering on the dirt. Only the Omeo Highway from Mitta to Omeo compares to this imho. Maybe the Alpine Way Khanchoban to Jindabyne. And possibly the Eildon Jamieson Road if you do a U-turn at the Jamieson end and head straight back to Eildon to make it over a 100km of hardcore twisties.
