Has anyone had a failure with this type tongue while towing with a large motorhome?

I once had a failure with that style tongue, and I was towing with my car!

trailer tongue. Regardless of style, the adequacy of any trailer tongue
is all about the engineering and construction. As always, the devil is
in the details.
