CT681 Features



You want a truck cab that combines the best of comfort and functionality—because a comfortable driver is a safe, productive driver. The CT681’s spacious, ergonomic interior delivers.

Get Shift-Long Comfort

With multiple seat options, a leather-wrapped steering wheel that tilts and telescopes and premium sound insulation, you’ll enjoy a quiet, comfortable ride.

Work More Safely

An ergonomic dashboard and center stack, well-illuminated interior and combined standard and convex mirrors come together to enhance safety.

Access What You Need

There’s plenty of room for paperwork, log books and more in our easy-to-reach side compartments, back-panel storage and oversized side pockets.



Those who’ve seen the CT681 up close say it’s built like a tank. That’s because we’ve designed it to work hard and last for years, even on the toughest jobsites.

Carry More Load

This set-forward axle model features 114-inch bumper to back of cab (BBC) and 28-inch bumper to axle (BA) lengths. It’s available in 6x4 day-cab.


Mount Attachments with Ease

Our integral Front Frame Extension (FFE) option makes it easy to mount snow plows, hose reels, winches, hydraulic pumps and other attachments.
