Entire undercarriage is covered in rust. All control arms and linkages are in extremely poor condition from rust to the point I wouldn’t feel safe driving it. Let alone using it for its intended purpose for heavy duty towing.

Powerful, dependable, quiet interior and looks great! The duramax with the Alison transmission is the best diesel on market!
