Great job, I do have a question. Why would you not want to do something like a piano hinge across entire inside width? My thinking is as long as you are dumping level or straight per say, its not a problem. but if you back up and say the back is at a angle and you begin dumping, the contents will naturally want to move to the lower side and puts more force on that side and possible will make the bed twist to some degree. The piano hinge gives it more support across the whole width than just 2 pin locations.
