This truck was built to help you tow heavy things on a daily basis, whether it’s short or long distances. Whatever the job calls for, the 2015 GMC Sierra will get it done.
There’s not a whole lot of daylight between the Sierra and its more mainstream heavy-duty truck cousin, the Silverado. Like the Silverado, the Sierra HD doesn’t lead the class in towing numbers, either.
