Well we could definately do with more wranglers at the Jeep club.
Most of the TJs there seem to have 31s and a 2 inch lift of some sort.
No extreme mods.
I talked to another TJ owner at the club tent at the Adelaide 4x4 show today.
I know what you mean about Cape Jervis - next time you need to just go straight to Fishery Beach after a rain. Forget the national park.
The border track sounds like it has some closed sections (some of the dunes) but there looked to be (on video) a fair amount of rutted track driving and some sand driving.
I didn't go, so what would i know... if you post a question about it here:
