This is exactly what I needed. My wife and I built a "crate system" for the back of my 2007 Suburban, but instead of using crates we used a trunk system that gives you top access to storage. I couldn't find many options that would allow us to block the top and prevent the content from bouncing and these items worked great. I like that you can make adjustments, although I wish it had come with screws. In terms of durability, I hope it can withstand abuse.
