Bought a roof rack off E-bay which cost $229 plus $25 dollars postage. It has three Racks to hold the load and is made of Aluminium to keep weight down (More weight equals more petrol).
Hopefully I should be able to attach my awning to them without to much fuss. Want to put some Marine Ply after making a light aluminium frame to hold the ply. This will act as a base from my future solar system and any things like crab nets or other dirty items. And provide a bit of shelter for the roof.
