Wow the F-250 isn't meant to go over 65 mph before it simmys and shakes. After the truck begins to vibrate violently the guy calls the dealer to find out what's up. The dealer actually tells the guy the F-250 is not meant to go over 65 mph it is meant to haul stuff. He goes on to say if the guy wanted a race truck he should have gotten an F-150. WTF!?! Does that mean You can't take the truck on the interstate? Ever?
