In my last land cruiser I just layed it flat in the cargo area and strapped it down and was ok with it. This time around I did some more thinking and tried to come up with something that allowed more room for groceries and stuff in general. I was going to throw it on top but didnt feel safe with the factory roof rack holding it down on the highway. plus the sun would eat it alive. what I ended up with is VERY,VERY sturdy. I used two 500 lb ratchet straps and just stood it up. does not have any side side or front to back movement. Now I can place things on both side as well as behind the tire. Not anything to crazy but it gives you the ground clearance you need in the rear and doesnt take up to much from the cargo area and is safely secured. and yes I know I need to clean the carpet.
