Interesting. The military HumVee uses the 6.5 GM turbo diesels that were shyed away from by GM pickup truck owners. Apparantly the military thinks that is a great dependable engine. When they came out with the Duramax, they opted to stay with the 6.5 TD. Of, course being a military version, I am sure it is much more dependable than a civilian 6.5.
