Woodbeef- I guess Jay has not seen this post so I will try to answer if I can. The biggist thing you will see at first is the change in looks (more like Forterra), and it has the Forterra engine, tier 2 EPA approved. The shuttle has been change from 10/10 to 12/12, and the shuttle shift will also be synchronized. The new engines have greater torque backup 30-35%, and are about 5% more fuel efficient.
