Anyone have any nice clean solutions for a mat/lining to lay on the bed of the truck so that things don't slide around in the bed? I don't care too much about protecting it since I'm usually just storing containers or other misc surf gear, or when shopping, putting grocers in those bins. But as I accerate/brake or make turns, it just keeps sliding around and banging around in the bed. I'm thinking some rubber mat that was shaped in the shape would alone, stop it from sliding around so much. Any ideas?
