Mike are you basing all of your GM diesel opinion on that 6.5 you had? That explains a lot.
Ain't it AMAZING?
No offense against Mike, but basing your hate for GM diesels because of owning a bad 6.5TD is like basing your hate for a nice flat screen TV's after owning an old Sylvania 19" tv with tubes and rabbit ear antennas.
I had a 6.5TD that wasn't very good either, but eventually I got over it.
