towing a caravan 14foot pop top

Hi Captaim.
I did the same trip last July towing an off road camper trailer.
We passed numerous vans between Eulo/Hungerford & Wanaaring/Tibooburra.
Currawinya NP is a great spot to camp & explore & we camped near the old shearing shed not far from the Rangers station.
The roads were quite good them however I don't know how they recovered from all the flooding.
Our first night was spent at Nindigully. A great spot with an old pub nearby.
The Hungerford pub has great counter meals.
Enjoy your trip. It is a great part of aust.
Regards.

I did the trip from Eulo, Hungerford, Wanaaring then on to Wilcannia towing a Jayco Penguin Off Road last September. Really a typical outback road bad sections of corrugation with some good sections.

If you're not towing an offroad van or one that doesn't have what is commonly known now as dirt road suspension just drive to the conditions and take your time otherwise you might do some damage.

Currawinya waterhole is a nice spot for a few days camping Lake Wyara and Lake Numalla should be full of water with the floods they had down that way earlier this year and would be worth a visit, both were dry when I was there.

I'm heading back out that way around August.

Yes you can do all these roads with your van provided you drive to the road conditions and lower tyre pressures on all wheels to help absorb corrugation shock, And do drive steadily.
We have done this trip a couple of times with the rig Pictured below.

I recommend this camping spot and leave your van for the day trip to the lakes, which should both have water in them now.
Our van was safe both times we camped there.
