I just bought my 2017 GMC Sierra SLE KODIAK Z71. It came with the original Monroney Sheet (window sticker) and it's written in French.
My truck has KODIAK badges on the doors as seen in attached photo.

• Dual zone climate control
• 10-way power driver’s seat
• Manual tilt and telescoping steering
• Rear-window defogger
• Rear vision camera
• LED foglamps
• LED cargo box lighting

• 110-volt AC power outlet
And fancy badges lol
