If you had a blank check to build a classic truck into the ultimate off-road machine, what would you create? For Andrew Knudsen, the answer was this Ford F100. By his own admission, there's not much left unmodified, but the timeless style and character of the classic F-Series is still clearly visible. Beneath that, it has a custom tube chassis, long-travel suspension, 40-inch tires, an 830-horsepower V8, and a surprisingly luxurious (yet highly functional) interior.
