Bought my f250 RWD XL Utility Truck back in 2012 for a song and at 270,000km/168,000mi she is still going strong!!! She is a little ugly from the previous owner but the engine purrs like new, the interior is still in great shape and there is virtually no rust on the body! I have fallen in love with Ford trucks. Simply awesome and easy to fix!
I bought the truck used back in '05. The previous owner must have had the engine injectors and turbo changed (a common problem with the first 6.0l diesels), because this thing has been a powerhouse for me, never a problem. Now that its getting older, and has 100,000 miles, I am still pulling horse trailers, and loving the power. My only qualm is a weird rattle from the frame SOMEWHERE (can't seem to find it when not moving). I couldn't be happier with the truck, and will probably hold onto it for another 3 years, then give it to my daughter as her first vehicle (she can pull her own horse trailer then!).
I have a 7.3 diesel. It's a wonderful hauler! The truck is very stable when hauling 2 yards of dirt or our 5th wheel trailer. I haven't modified the powertrain and see no need to. The economy of the diesel is about 14 in town and 19 highway; and about 11 with the trailer. Top build quality, over 100,000 miles and no squeaks. If you need to move heavy stuff, this is the one. If you only want a truck to look cool, the half-tonners are better for that. This is a serious work truck.
I own a '03 7.3L powerstroke, at the lake the transmission went out with only 52,000 miles on it. I took it to the dealer figuring the 100,000 mi powertrain warranty would cover it, it didn't. $ 4,000 later and the new transmission (refurbished I add) has a better warranty than the origional one. I'm dissapointed when I pull 14000K worth of equipment. I've heard wonderful things but haven't experienced the greatness of the 7.3L. Soon trade for a new twin turbo F-350 or a Dodge Cummins
My truck has been in the shop 21 times, 12 loaner cars, 5 repeats from local dealership and two tow trucks. Ford customer service is just at bad. This is the worst truck ford has ever made. Buy anything but the 6.0 Ford. Should this qualify for a lemon? Ford thinks not. Be careful and look for something else.
