Planning to do Barcaldine-Muttaburra-Tangorin-Hughenden-the lynd

You'll be fine if it's dry. Mostly unsealed road between Muttaburra and Hughenden and expect some corrugation. The usual story, drive to the conditions.

The road past Tangorin follows Landsborough Ck for some distance so it may be better to take the slightly more direct route that keeps to the higher country, past Dunrossie & Cameron Downs. I travelled this road in a Holden ute, over 40 years ago, and it was good travelling then.

However, for the sake of perhaps an extra 50-60kms, a better route would be from Aramac, north to Torrens Ck. All bitumen, except for the last 30kms into Torrens Ck.

Weatherzone shows sunny, fine days, read here 40°C & higher, so there shouldn't be any storms over the next week or more.

Thanks...my main concern is that 131940 reports most of those routes as 4wd only which means it's still wet but at least the weather is dry this week so it should only improve as we leave St George NSW tomorrow

You will have no problems with your rig.
I live on Cameron Downs station and travel these roads regularly.
The "4WD only" advice is due to the need for high clearance due to ridges between the wheel tracks.
The only problem will be if it rains, then all these blacksoil roads are impassable.

Mutta to Hughenden has NOT been graded for quite some time and had some good storms just before Xmas , 200km so so dirt , if really wanting Mutta and its new Dinosaur Interpretation Centre , Barky -Aramac - Mutta then backtrack 10km to the BowenDowns road , 50km dirt to the Torrens Creek Rd junction ,left to Torrens Creek ,all good bar last 30 km.....

Again, I suggest looking at what the Qld Traffic site says.
