The classic F250 was very solidly built. I have a 1985 Ford Bronco, which is an F250 chassis with a different body and was built to comply with the 5MPH bumper standard in effect for a few years. It was once rear-ended while stopped by a SamTrans passenger van. The SamTrans van front end crumpled properly, leaving its nose on the pavement. The Bronco had a bent trailer connector and a broken license plate lamp housing.

12MPG, though.
