I now have 6,600 miles on this truck. It has been in the shop 21 times in those few miles. The brakes are soft and when pressed down in a medium braking situation, the brakes go down below the gas pedal. It has made for some pretty hairy stops. As far as the gas mileage is concerned, it is really bad. I would not reccomend this truck to anyone. It looks like Chevy copied Nissan and then threw it together. The center arm rest is so cheap that I am afraid that it is going to fall off if I put my arm on it.
The push button 4X4 control, and I hope that keeps working.
Take the truck back to the drawing board, and come up with something better than Nissan, Totyota, or some other foreign made truck.
