I found a project truck, 'The ultimate F150" and he had a z-bench on the truck. I looked it up and it looks like a pretty good deal. I have never seen anything like it. It is more than a step. It makes your tailgate a table and can be a cargo holder and the best thing is it folds up to about three and half inches. Made of aluminum they have a picture with over a 1000 pounds on it. Something to consider I think I am going to get one. There was also a video on youtube, http://www.youtube.com/watch?v=fRgraeIQuec
