I have had problems with rotors since I bought truck in 09', a month or 2 after I bought it I had rotors changed and then every 3 to 4 months after that. My front wheels are black after 2 weeks of driving. I have never pulled a trailer with this truck and this truck has been used lightly. Also after 12 years old, mechanic told me yesterday I have a year or 2 before my frame is going completely rusted thru and be dangerous to drive.
