You also don't get it from building a solid steel box. And you keep missing my point. A hitch is a lever. If the cross beam was not built for that bending moment, it will deform. That has no bearing on a torsional force. Only if it was built to have the vertical and torsion loads. No need to stereotype, I tow and haul. Thus waiting for the pickup... I get that you would like to haul, I hope Tesla made the 3 easily capable of such a thing, but I also understand why they would not have (time, money).
