How about 6.5 tons in a 91 f250? I was hauling used concrete slabs to the landfill. When I arrived at the scale the operator stared in disbelief for at least 5 minutes. No damage to the truck except the dump bed fell off the frame! Had to stick 4x4s between the frame and the axle so it wouldn't drag the ass end. Believe it or not the truck is still in service at our company!!! Hows that for overbuilt? I had no idea a few slabs of concrete weighed that much! It was my job to repair the damage I had done though, after several hours of welding I learned all about severe metal fatigue….
