2003 f 550 runs good, transmission shifts smooth, ac works. I have had a computer diagnostic from a local Power Stroke Diesel Shop, and you can see the results in picture. The truck needs a new gas tank, fuel pump, and like all older diesels the oil leaks.The Aluminum Flatbed cost me $7500. This truck has many years of work left. I will help you ship anywhere in the States.Any question , I can be reached @ 239-204-1062 here
