Welcome to the group. We didn’t do the Tanami but cut across on the Buchanan highway. It was good, except thought the Gregory NP, it was a bit rough. We tow a XC with a Patrol and had no problems. If you are heading for Broome (we are here now, parked next to another Kedron) . Two overnight spots I can recommend, Mary Pools, and Lake Ellendale, both are on Wiki Camps.
