"I bought this 6.0 Powerstroke diesel truck for heavy-duty hauling. It pulled very heavily loaded trailers great distances with no problem. It is a workhorse. It takes attention to detail (routine maintenance, no aftermarket parts). It probably needs to be bulletproofed (modified with upgraded parts) to run well past 100,000 miles. If you need a work truck it is great, but for city driving or off-roading I would not recommend it. As a diesel, it gets about 15 mpg, and maintenance and repairs are expensive. "
