I had one on a one ton parts truck. It was very close to 8'. The half ton had rear fenders under it and it was about 6 1/2 feet. I should have a photo of this factory script bed mounted on a '32 1 1/2 ton. It was too short by a foot, but this '32 had been bobbed off as it had been a coal truck, so it looked ok. I will try to find a photo.
