northwest missouri | Don't know - I have a '99 2500 w/ 6.0 that will get 15-17 out on highway, always right at 13 for normal farm use & short trips when not pulling trailer - just got an '08 ( not broken in good yet ) that won't get anything over 12.5 ( and that was on a 250 mi road trip, all hwy ) salesman told me that this new one would do better than old model because of gearing and variable valve timing - surely didn't have anything to do with his motivation to get money from my pocket to his ! | |
