Ok, 3 part question here: - What keeps the racks on when you dump or is this not an issue? - I have seen pics. of a similar stake body dump truck w/ ~2" pvc pipes on end (in the dump bed, closer to the cab) for hand tools such as rakes, etc. What keeps these secure when dumping? - Has any1 or does any1 have a "shelf/rack above the cab for something like wheel barrow storage? If so so, was it a custom job or installed from a dealer?
