"My '04 Super Duty has been great until I started pulling my new horse trailer. So far, one head gasket and on my most recent cross country trip, one EGR cooler. I took it to a Ford truck Center in California when the EGR cooler went out and was told by the Service Rep that he had the same engine in his truck and worried about it everyday. Said the 6.0 is great for a family vehicle, but when you put a trailer on it, or heavy duty use, the engine just doesn't hold up. Of course that made me feel better, considering I only have 40K miles on it and already have been on the side of the road with it twice."
"Overall very satisfied with the 7.3 diesel. Really happy I did not buy the 6.0. Once broke in it got great mpg. 18 before the chip, and 20 with the chip. Towing my 30' fifth wheel camper (13,000) lbs, 14mpg. Had to replace rear wheel bearings at 38,000, ball joints at 52,000. Truck is up to whatever I put behind it towing, and has a nice, much quieter inside than previous powerstrokes. Also rides suprisingly well for a F-350. Not looking forward to trading this one in. Not at all impressed with the 6.0, or the new 6.4 twin turbo. Both lack h.p. compared to the other big 2. Ford needs to go back to the old 7.3 diesel. Why fix what wasn't broke?"
"I own 2 2002 models, and other year Superduties as well. I have never been left stranded by any of my trucks, and they perform well in temps in the neg 20's, thats as cold as I have gone in them anyway. I work from them and play from them, I use them in all facets of my life. To put it simply, the Superduty trucks will always be my first choice."
"this truck has held up yery well. it has some rust but that is to be expected, it has never been waxed, rarly washed. love the fuel milage it gets 18-20 mpg. not any problems with the motor. 7.3 just love it. hope to get at least another 200,000 on it if not more."
"best vehicle I've ever owned. I put all the miles on it, and it has been extremely reliable. 7.3L is the best engine Ford has ever made, bar none. Wish it was still made, but it's longevity prevented them from selling new trucks as replacements."
