Hi, my husband was the XXXXXXX man in 2008 # on your list. XXXX had 20 years experience driving and pulling trailers CDL license. I know our hitch broke before we rolled I saw the trailer coming up on the passengers side.It was a brand new hitch right out of the box that day . it looks to me as a bad weld. We are still looking into that.He is greatly missed and our lives are forever changed!
