It's a very old Mack truck. Unlike the Anthem which was all new, this other Pinnacle truck is a step backwards in that they put lipstick on a pig. I very much prefer the older more rounded Mack Pinnacle to the new one which seems very out of place to be its successor. I could see it as a different named truck, but not a Pinnacle. It fits the Granite more.
Original Mack Pinnacle.
The 'new' ugly Mack Pinnacle.
The Mack Granite seems more like the new Pinnacle. So why did the Pinnacle become a rounded design truck to a square box that looks like it came from the 1970s?
