New GR64B with the Mack MP7 355HP engine and Allison 3000RDS transmission, it's lighter weight and cost much less, but still allows you to haul the big loads! Along with the 315's all around, this chassis is the perfect setup for multiple different applications, from a rear loader, dump truck, septic body, and various other needs. On top of being a Mack truck at a lower cost, these units were built just prior to the "tariff fees" so you'll save even more!! Several units on the ground ready to get bodied up.
