alpineway what's it like??

hi, we are starting to plan a 5 week holiday in sept/november this year and couldn't workout where to go, we live at goolwa - down south of adelaide and a friend mentioned the alpineway and it did sound nice, is it as good as it sounds? and is the road suitable for towing a caravan on as our friend said it wasn't years ago when he was there, what things are a must see and what caravan parks or free parks are good or bad in the area?. i was thinking of ending up in canberra and follow the coast towards home, so info on doing that too would be helpful.
thanks for any help from chris.
