I see that the 'ball hitch' has become the focus of this thread. Please keep us updated on the cause of this crash. I've seen trailer balls in the store that are 'quickly-interchangeable' by sliding different size diameters over a straight shank. No thanks....not for me! In fact, I have an expensive Stainless Steel ball on the back of my Duallie and sometimes I look at it and hope that it's not that same soft stainless steel that hardware store bolts are made from. Those hardware store stainless bolts are extremely soft and twist off easily. I'd hate to have a trailer hitch ball of the sale material.
