Sorry, this is the correct one http://www.4x4australia.com.au/explore/nsw/1308/tenterfield-nsw/
You could make a day of getting down there, instead of just tarmacing it all the way. We could go down the Mt Lindsey Highway and then through Toonumbar and the Richmond Range national park to the Bruxner Highway then head west toward Girard National Park. I have driven the through those parks previously and they are a nice drive and you would be able to tow your trailer no problems. Then we could set up around Girard and explore for a couple of days, before deciding whether we just want to head straight home or find another route on the Monday.
Alternatively, Rover park is in the same neck of the woods.
