Just seeking opinions on a used Duramax

Thanks for all the replies so far. I've looked at a lot of used trucks in that price range in my area and the diesels and gassers all seem to have 150K+. I guess people in Texas drive the hell out of them. What caught my eye on this one is it is very clean and it seemed odd the previous owner just put brand new tires on it. I mean you can still smell the new rubber smell on them.
