A simple solution that works
Such a simple idea that helps bring organization to your truck bed. I'm using it to immobilize my gear when overlanding in a Jeep Gladiator. I haven't been able to test it on the trails, but so far it works as needed in the city (I tried jumping some curbs to simulate rocks.) The other great part is that I can easily remove the blocks when I want to use my bed as a truck bed. It's also easy to clean.
