used 600 with 12.7 DD

You'll never find one with a 14L Detroit. I think 2000 or 2001 was the last year for 12.7L in KW. A buddy has a '99 W900 with one great fuel mileage once he got rid of some boost leaks from previous owner. Check truckpaper and craig's list.

 

here is a 2003 non egr 12.7, and probally going to be the best for OTR trucking.

Now that truck has some real tread!

 

It's got legs too. 3.55 and 11/24.5! Those S60s like to sit around 1450+
