Old Dunstan Road

Hey team, some advice from those in the know if you please....
Heading to the Mainland for 3 weeks with the family late dec/Jan for 3 weeks.
My question, obviously depending on the weather before and on the day will a 2wd ute be all good over the Old Dunstan Road?
Ridden it on a bike 10years back and seem to recall a few mushy spots, so keen to hear some more recents experiences of the road.
Thanks in advance.....cheers Dave

According to my DOC mate, the eastern end of the Serpentine Road is impassable due to a damaged bridge, but if you stick to the slightly more northern Old Dunstan Road you should be OK at that time of year. Take a shovel, etc, just in case.

Thanks @gundoc
