actually just saw the Aussie Q5 accessories brochure - one is the tray one is the liner they are different productsHi Rick,
I think you will find the first one is a rigid boot liner and the 2nd one a rubber mat type.if you have specced the storage bar in the back im not sure if you could have the rigid boot liner.The rubber mat comes in 2 forms one for the bar with cut outs and the other a solid mat.
hope this helps
Will drop my dealer a line
As a secondary point really want to keep the load area free from scratches as I will be using it to transport a lot of diving
Anyone had experience of this lot?
