Mack Trucks? Best model for Heavy Haul?

All you need original big power right here

 

I have a 2012 pinnacle and it’s issue after issue.

 

We use '21 Pinnacles. 10-speed, manual, de-nutted to 65mph. Dragging around 100,500lbs gross at a time (tandem tare = ~29,300 / 31,500 dependant upon cubic capacity of bulk tank).... But I've moved 102 w. it.

194k on the odo. Only real issue so far was the DEF thermostat & a short in the ignition.

 

2012 was a bad year for Mack. The company at the time, McKenzie Tank lines bought around a dozen that year and everyone of them was a disaster. They were sold off quickly. The 16, 17 and 18 year models are still going strong.
