2012 Ford F-450 Super Duty (6.7L Power Stroke) — Should You Buy One?

Typical asking price: $26,000–$42,000. There are 3 high-severity known issues you need to know before handing over a check.

Kestrel Take

The heaviest single-rear-wheel-equivalent Super Duty, built for goosenecks and fifth wheels at the top of the tow ratings. The first-generation 6.7 Power Stroke is strong but early, and it uses the CP4 fuel pump. Commercial-use wear and the fuel system are the risks.
