Holy shit. This is the part of the frame that connects the 11k lbs rated hitch.
If you watch the entire video, not just a dodgy misleading clip and engagement farming headline, you’ll note that prior to towing he damaged the hitch and frame by:
Ramped it at a horrible angle with a hard landing, ran it over logs bottoming it out repeatedly, then drove it off 8 foot concrete tubes with the back end crunching on solid concrete damaging the hitch and frame before he even attempted to do any towing.
Those details don’t make for a good gotcha post in a cybetruck hater forum though.
