It was a factory hitch. The problem is you can not see that the frame is failing above the crossmember which holds the reciever, you need to look with a mirror above the crossmember and check for cracks in the frame extension that holds the bumper. I am a commercial driver and owner operator for many years, I also do most of the maintenance and repairs on my logging truck and still was not able to notice that the hitch was going to fail. I did a visual just 7 miles before it failed. I suggest getting it checked or maybe just go and get it replaced with a normal hitch that is bolted to the main frame and can be easily inspected.
