2015 Cornerstone Model Overview
A CAB IN A CLASS OF ITS OWN
You'll rule the road thanks to a Cummins ISX 600 HP turbocharged engine. (And with Cornerstone's well-appointed cab, you'll rule it like a king.) Eight-way power seats and SmartWheel integrated steering make the ride comfortable, while touchscreen technology and the optional Mobileye make it an advanced ride. Now, that's cab-forward design.
