GMC sierra 2500hd Denali is a great truck.
My truck has 60,000 miles and I have had no problems with it. Normal wear and tear but it is holding up nicely, interior, paint, engine, transmission. Performance is great. My GMC sierra 2500 has no problem towing our fifth wheel camper. It has many great features such as heated and ventilated seats, power mirrors, heated steering wheel and 4x4. It is a great truck that tows well and my family of four fits comfortably on long rides.
