In Dartmouth and across the Maritimes, that kind of traction matters through winter, mud, gravel, and changing weather. The engine block heater is also a practical addition for cold Canadian mornings, helping this truck feel ready when temperatures drop.

Inside, the cabin balances work-ready function with upscale touches. The Black interior gives it a clean, durable look, while the sunroof brings in natural light and adds a more open feel for everyday drives. The Head-Up Display is a standout feature, placing key driving information in an easy line of sight so you can stay focused on the road ahead.

This truck is well suited to drivers who tow, haul, travel, or simply want the confidence of a heavy-duty pickup with premium appointments.
