Pinnacle™ Sleepers — CONQUER THE OPEN ROAD
The Mack® Pinnacle™ Sleeper is built on a lightweight-yet-strong frame specially designed for heavy loads, steep grades and long hauls. It runs on a powerful and fuel-efficient MP engine that delivers the brawn you need to handle your payload and the fuel-efficiency you require to run longer and maximize profits. Add to that our industry-leading electronics; ergonomic dashboard; quieter, galvanized steel cab and plush interior with plenty of storage and a thick, innerspring mattress, and it’s clear you’ll feel at home on the road. Available in axle back and axle forward configurations and five models (48”- and 56”-flat-top, 60”- and 70”-mid-rise or 70”-high-rise), these trucks are suited for overnight and regional hauls or long-distance runs.
