Ford Super Duty trucks are true powerhouses designed to work hard. They include the F-250, F-350 and F-450. Standard power comes from a 6.2-litre gasoline V8 engine, but there’s also a 7.3-litre variant and a 6.7-litre turbo-diesel V8. Maximum towing capacity ranges from 22,000-37,000 pounds depending on the model. If you want best-in-class capability, this is where you’ll find it. Also, don’t miss the outstanding Tremor off-road package.
