My father in Law has a 150 Prado, absolute pearler of a machine.
He purchased it when they first came out to be his touring vehicle. From new he had a 2" lift with Dobinsons coils, and Bilstein shocks installed. He also has airbags.
He has crossed the Simmo, Canning, and been to the Cape via OTT, and a few trips to Fraser.
He has had zero problems with his setup, and couldn't recommend it highly enough.
+1 For Bilstein
