Other mechanical differences between diesel Stage 1s and Perentie include the engine (both are 4BD1 variants), the braking system and the drivetrain components.
It is a matter of debate as to which could be the toughest but I'll say one thing - the coils are easier on you back :)
Some 4X4 Perenties come with power steering and it can certainly be easily fitted to those without - it's a feature I find essential.
