Yes, this was covered this past week under "Tow Vehicle" I believe.
The 7.3 Power Stroke is a proven engine with a lot of after market support. My 99 Super Duty Crew Cab has 135000 miles and is going strong, no problems. I have a superchip program and Magaflow exhaust on mine and get 18 mpg, plus it runs like a spotted ape!
The down side of running a diesel is the cost of preventive maintenance. It is a lot higher. 14 quarts of
oil and a $10.00 filter every 3000 miles,$25.00 fuel filter 15,000 miles, coolant additive every 15,000 miles and so on. But who's counting.........
Hope this helps
