I would think the NTSB would mandate that the suspension, brakes and tires would at least meet safety standards and NOT cheap substandard tires( China bombs ). As all my vehicles, those come first as they are what keeps me safe on the road. The rest is up to the manufacture. If they build poorly constructed rigs, then the word will soon get out and they will suffer drop in sales. I expect to get what I payed for and not thrown together crap.
