Quite agree 2 weeks is not long to be up there and as I have said you are more than welcome to stay up there longer and side track around. We have been up the track to the Cape twice before (along the track) and looked at the place so this is more to accompany anyone else in the harder parts that wants to do the run up the there. The tracks are narrow in places but we have had no trouble getting through even the first year when we had the slide-on camper on the back. Nice stuck you have there - it wouldn't back out of there ?
The Landrover looks to be having trouble at Palm Creek heading south and may need a bit of a pull to get him out of the road.
Not sure on weight of my rig but yes it has modified front springs (been lengthened 25mm from centre bolt back and more set). Same deal with the rear and I have left the helper but it shouldn't really sit on them. There are a lot of different ways to try and improve the Canter ride, I see you have gone for air bags in the front and coil assist in the rear with traction rods ?? Dirt -- you have seen nothing yet, mine is no different as it is a vehicle that I use and not sit in the driveway to admire.
