Hi AT.
Mate we could debate the merits of Chinese metallurgy & said processes all night, but my knowledge in that regard is pretty limited so you would win hands down. But this is what I do know, the shock loads that are exerted on the tongue via the tow ball would by far exceed (in my estimation) those that were exerted on it from the collision with the mates ute, the hex indentations on both sides of the tongue have reduced the thickness of the plate, that in it's self would compromise the strength of the steel.
The crack runs along the back line of the hex parallele to the bar on the underside so if there is going to be a failure line from being pushed that's where it would be. If it were from being pulled the failure would be on the topside, anyway I think these arguments are secondary to the main game & that is, the tongue cracked. If one is prepared to accept that, & some seem to there's bugger all I can do about that, I guess my standards are a little higher I would expect this item to withstand the rigors of its towing capacity over a lifetime. On occasion I have exceeded the rating of a hitch with caravans & trailers & have bent the tongue, but never cracked it.
To run another scenario, had I been backing the trailer up & had hit some thing the same result would have occurred, had I not noticed it & was going down the road & drove over a trench that had been dug across the road, you know the ones that the filling subsides, bang, shock load going the other way with the likely hood of snapping the tip off the tongue!!! I'll leave the rest to everyone's imagination.
Bottom line is I think it's a dodgy item & needs to be investigated!!!
Cheers 2TGs.
