My father in-law is looking at an 04 Chevy 3500 duramax/allison with 53,000 miles. Does anyone know of any problems that he should look for? Any comment are greatly appreciated.

 

If its a LLY there prone to overheat! If its a LB7 there an all around good truck! Always check for codes! The only major Thing I can think of would be injectors seemed to be a problem on most all the first duramaxes!
