They all have trouble IMO. The reason we buy 6.0 is because you can get them cheap, bulletproof and mod them for less then you would spend on a beat up 7.3, at least in my neck of the woods. Old 7.3's sell for around 5k more then I paid for my 6.0. So basically I got a 6.0 because I needed a diesel and got a great deal and knew the weak points. I choose to get those addressed before they bit me in the you know. So I guess my advise would be get it cheap dump the money needed and have fun. They really are great trucks if you do the proper work AND have that work done CORRECTLY.
