After having two Z71 Suburbans, I gave in and purchased a truck that could pull my 30ft. RV and still be driver in the city. This is a great truck, quality is tops. I have almost 4000 miles and have not had any problems. I have also noticed that once the truck warms up, the mileage is not bad for a big gasoline engine. I have averaged 16 on the road and around 13 in town. Considering the size, power etc. this is not bad. The six speed transmission is great for pulling. My RV weighs in at about 7500lbs and you can't even tell it's there. I have driven in North Carolina pulling the trailer in the mountains with no issues. I haven't missed my Suburban.
Power pulling a trailer. Bose sound system. Comfortable interior.
A little more room in the front wheel area for larger tires.
