We had a 2000 Mack and a 2001. I don't remember the model numbers because I'm not that familiar with Macks but they were great to start out with, then they started lacking power, parts were getting harder and harder to get, service sucked, fuel mileage sucked, and the overall durability wasn't the same as our Internationals. So we traded them for a 2005 International 9900i, and a 2006 International 9400i

Epa is the reason the 12.7 60 series, Cummins N-14 and Cat 3406 are history now right? I thought all those were good engines in there own way.
