The 2008 Ford F-550 Super Duty is a workhorse in the heavy-duty pickup truck segment, known to be especially rugged and versatile. The fourth generation truck offers two engine options: a 6.8-liter V10 Triton gas engine with 362 hp and a 6.4-liter Power Stroke V8 turbo diesel with 350 hp. Both are mated to a five-speed automatic transmission that sends power to either the rear wheels or all four wheels, depending on the configuration. The F-550 is available in XL, XLT, and Lariat trims. Noteworthy features include a highly capable towing capacity, a spacious cab, and hard-wearing materials designed for durability. It doesn't bristle with the latest tech, but does offer an optional navigation system.
