Truck is a blast to drive, very quick and responsive with the 6.2L engine and 10 speed. Gorgeous looking truck from the outside. Interior styling, not so much...

This will be the truck that you've always been looking for. It has everything you could ask for and more. The safety options alone are outstanding. You won't be disappointed.

I have never purchased a vehicle requiring so many recalls. Was this truck not finished at the factory. My previous vehicles have all been ready to use without recalls. Are customers your way of testing and finding your problems?

Do not buy this truck because the big selling point is the new TAILGATE feature but little do they tell you it's a set up for Disaster
