This is a new frame, developed with the latest engines in mind and sharing a number of features with the Volvo frame. Underhood temperatures are expected to be an issue again with the greater heat, so underhood air management is highly desirable.Īnother major change, although it's one that carries over from the latest Vision models, is the Mack Advantage frame. As in 2002, cooled EGR requires heat rejection to the cooling system 2007 sees higher rates of EGR with finer, closed-loop electronic controls for even tighter NOx control. This allows for the critical air handling under the hood that was the subject of much research and development for the new models for 2007. The new engine, the MP7, is shorter than the old – very old – E7, and sits back in the frame. The Pinnacle also sees styling changes that have their basis in the need for more cooling for the 2007 engines. New doors with lowered beltline toward the front aid visibility, as does a one-piece windshield option for the Pinnacle.
#MACK PINNACLE PRICE DRIVER#
More recently, the Granite has had a revision to the back-of-cab to address the front-to-back room of the old cab, along with running changes to dash and seat slides that make the cab an acceptable driver environment. The CH had a major styling change with the introduction of the Vision over-the-highway trucks and, more recently, a ruggedization with the modifications for the launch of the vocational Granite. The Pinnacle is the latest evolution of the CH, although really, only the basic cab structure remains. The haul back is 20 of the recreational machines. The run up is with an empty to stage there. Polman also hauls "four wheelers," ATVs from Roseau up close to the Manitoba border, which is where we're heading on this evaluation. Today, Polman's freight is lots of French fries (the local soil produces a particularly white potato much favored by McDonald's). He has overseen test units for previous Mack engine/electronic changes over the 26 years he has been with the company. Wally Anderson runs the shop, and chooses trucks, components and all mechanicals.
Over time Duane Polman has tried other brands, but remains a staunch Mack account.ĭuane still goes in to the office every day, but the company is now run by his sons, D.J.
