I have owned nothing but Toyota trucks and SUV's for the past 30 years, when it came time for a truck I traded my 2011 4R for a 2014 CPO Sierra 1500 CC Std bed 4X4 Z71 with 5.3L and 3.42 rear.
So far I am enjoying the truck, I hear Toyota owners bashing the American made trucks but after talking to true GMC and Chevy truck owners who have nothing to say but good things about their trucks I decided to give one a try. To be honest my last few Toyota's were far from trouble free, Had transmission, torque converter, manifolds, fuel gauge sending unit replaced on 2002 Tundra before 30K mi. Had front differential and axle replaced on 2011 4R due to internal bearing failure at 46K mi. Did not abuse or take off road either. I needed a V8 truck to pull my boat and after driving a Tundra I liked the Sierra better so here I am. Time will tell if I made the correct choice.
