Hi Triton
We went to Merimbula from Ballarat at Easter via Gippsland, not a bad road but can be boring.
We then returned to ballarat via Jindabyne, and then to Albury, on the Snowy Mt Highway. We were towing a 17.56 expanda with a current model challenger. It is a very scenic route, and over all a pretty enjoyable way to go. However there are some very sharp and steep inclines and declines, we had no trouble with this and just took our time, the road is very narrow at points and you will not get 2 vans side by side on it. We found, that travelling earlier in the morinig was best as the amount of traffic was very low. we also found that most people were happy and all you had to do was work in with each other when passing and allow time. It took us approx 3 hours to travel approx 130km but yes we did it.. Also you will need a Park Pass to travel the roads, or just a pass through pass which allows you approx 2-3 hours to travel the road through the park BUT you Cant stop or you risk being fined.
