NT near Tennant Creek: Where to park our caravan for 2 weeks?

[Jack Lucy & Josh]

Hi,
we'll be heading south from Kathrine NT today and we have decided to leave our caravan at Tennant Creek behind.
Plan is to go to Uluru, Kings Canyon, McDonald Ranches, … with tents and 2 weeks later pick up the van again heading east on the highway.

Question: Anyone near Tennant Creek that can accommodate our 17ft expanda or maybe knows someone who knows someone …
TIA!

Bunka Bunka station were very helpful and let us park our van for 10 days.
