This is the Excursion that actually matters: a 6.0L Power Stroke diesel with a five-speed auto, limited-slip, and two-owner provenance since new. The 6.0 is famously fragile, but a clean, low-mile example from someone who didn't beat it to death is increasingly rare. Diesel truck values have held better than anyone expected.

This 2006 F-250 Crew Cab 4×4 rocks a heavily modified 6.0L Power Stroke—EGR delete, stage 2 Garrett turbo, SCT tune, aftermarket stand pipes. It's the kind of mid-2000s diesel build that defined a generation of truck culture before tuning became a subscription service. Clean examples with documented mods are getting harder to find.
