We just drove my D2 TD5 from Nuriootpa to Darwin and back this year.
Daly waters is good, Aeirleron ( hope I spelt it OK) is a great place to stop.
Do youself a favour and take a small very easy dirt road detor down from the highway 30kms above Glendambo down to Kinggoonya (pub and hotel where all the railways meet up - run by 2 ex army guys) and then back onto the highway at Glendambo.
Have a safe trip and let me know when/if you pass through the Barossa - have some nice Home Brew on Tap :-)
