Hi Alders
We were there a couple of weeks ago, we couldn't get our off road 22ft van in, there was a off road bush tracker 19ft van in there so thats about the limit in width and height
There is a couple of spots that will take a bit of skilled maneuvering, but he apparently he had no problems.
I do have the directions from wolf on my phone that are spot on to the gate if you need them.
Cheers K-M
