Hey all

Im in the process of organising a trip across the Nullabor.
Im not very mechanically minded, so I'm wanting to prepare my GU in the best way possible.
It is the 2001 GU 3.0 ZD30. And have done a fair few of the mods to keep on top of the problems.

My car is due for the major service, so i will definitely be getting that done.

What other things mechanically on the car can i do to make sure i get there and back.
Might be a silly question but as i said i know very little mechanically. I just know how to drive it haha.

Any info and tips would be fantastic.

Thanks
