Friend from Bend, OR had a run in with a logging truck yesterday, I'd say it was a draw... She came out battered and bruised but living and able to walk away...

 

She was very lucky, that is not even a 10 mph hit, probably 5 mph, and it happened on the soft spot of the truck. If he had hit her square under his radiator, it would have killed her. That logging truck probably has a double frame at least, which means it is a solid 1"+ of steel channel that is boxed.

Very lucky. One thing about the newer F-series is their seats are better at rear impact.
