I am afraid to drive at night because the head lights are terrible. I couldn't see the tire carcass left on the highway early enough to swerve around it. I hit it with the rear wheel and did approx. 6000. 00 dollars damage to the vehicle.
The new tow mirrors on this truck have led blinkers that are so bright you can't tell if someone is coming towards you when you have the blinker on. It's flashing right in your face.
