[quote=felix;25213]t'd be the Hilux or something like it but they seem overpriced compared to say the Holden-badged Isuzu.QUOTE]

Geoff Bragg - on this forum has a 92 Rodeo Turbo Diesel running on SVO.
I think he is happy with it.
Geewizztoo - Triton.
Navara (Nissan), Ford courier/mazda bravo other possibilities if you want a ute. Hilux Surf (4runner) is good if you want a wagon smaller than Landcruiser/Patrol size.
Any others? If you think of any ask here to see if anyone has tried it.
Afterthought: SsangYong Musso, Fititan has converted at least 1 of them. they are cheap and a good prospect with the 5 cyl mercedes diesel engine.
Good luck with choosing.
