Mack Defense and Phillips & Temro Industries (PTI) have partnered to prepare U.S. Army M917A3 heavy dump trucks for harsh cold temperatures, with an engine heating solution that allows the trucks to start and operate more efficiently and effectively in extreme cold weather.

When activated, the PTI engine heating system circulates warm coolant throughout the engine to provide even heat distribution. Thermostatically controlled heat distribution ensures fast starts for critical applications needed by the U.S. Army. Warming the coolant also reduces fuel consumption, emissions, and engine wear, all critical factors. When equipped with the PTI system, the M917A3 truck is designed to start in extreme temperatures as cold as -40°F and provides optimized cold start performance.

Despite last month's sales increase, May vehicle numbers took a downward turn.

Are You Tracking Your Fleet's True Total Cost of Ownership?

Bobit Business Media surveyed 190 fleet professionals and found that while most fleets are tracking costs, fragmented systems and data gaps are keeping true TCO visibility out of reach. With rising pressure to control spend in an increasingly volatile environment, the gap between what fleets think they know and what the data actually shows is wider than you might expect. See how your peers are managing costs today and where the industry still has room to improve.

Cover of a whitepaper titled “The Hidden Costs of Departmentally Assigned Vehicles on Your Fleet” featuring a black fleet vehicle driving on a road at sunset. Subheadline reads: “Discover how your fleet can reduce costs and minimize risk by implementing vehicle sharing.” The document focuses on fleet optimization, vehicle sharing, cost reduction, utilization tracking, and risk management for fleet operations.

The Fleet Efficiency Gap: Where Budgets, Utilization & Risk Collide

Departmentally assigned vehicles often create hidden costs through underutilization, poor visibility, and increased administrative burden. This whitepaper explores how shared motor pool strategies help fleets reduce costs, improve accountability, and optimize vehicle utilization.
