I went to get my F450 dump truck on Thursday. It's a great truck. The contractor dump box was only used as a dump bed, so the drop-side latches and levers were neglected and rusted tight. With a little hard work, a big hammer, some heat and penetrating oil, I managed to get it all freed up and working. Both sides now drop down and swing on their hinges. I also managed to get the spreader gate controls and locking arms to move properly. The dump box can now be loaded from either side, as well as from the rear.
Other than a few blood blisters, some foul language, and a pair of jeans that are covered in grease and blood, all went well. LOL
