I own a Class B camper and this has been a topic of discussion on a couple forums. The OEM Promaster hitch is rated at 3500 lbs tow and 350 lbs vertical load. But those of us who throw a two bike carrier on there with a couple of ebikes are having the hitches fail even though we are only at approx 200 lbs. Well actually its the van body itself where the hitches are attached that is failing. The problem is the lever action created by the hitch bouncing is applying a lot more than 350 lbs of force. The further that weight is from the hitch the greater the force.
So my point is, this is not unique at all to Cyber trucks.
