I am quite partial to my 7.3 powerstroke super duty. The straight axle leaf sprung front holds the 1100lb boss poly v-plow very well, the truck tows like a dream with plenty of power and stability, and I have been able to put far more in the bed and tow far more than I should expect from a pick-up. It now has a little over 300,000 miles and has been pretty much reduced to wood hauler, top soil hauler (using a dump trailer), tractor, dozer, 5th wheel camper, gooseneck equip. trailer hauler, and in the winter MAJOR SNOW PUSHER! (I've plowed a couple of very large commercial accounts with the truck for 8 years. If we get 3" of new snow I plow for 8-10 hours straight, with big snow falls, sometimes the truck doesn't shut down for 24-36 hours.) Engine, transmission, transfer case, driveshaft u-joints, etc. have still NOT BEEN TOUCHED! Only regular fluid/filter/maint. I have had to replace brakes (lots), ball joints, wheel bearings, water pump (180,000 miles), serpentine belt (after 250,000 miles), and it now needs glow plugs, an oil leak, and coolant leak fixed (300,000 miles).
I know that the new Fords have had their problems and the Cummins has been very proven as a work horse, but I almost owe it to Ford to buy my next truck from them. Granted, the paint is starting to fall off the truck, but the interior still looks like new and isn't falling apart, all on a 10 year old truck.
