GMC Sierra 3500 HD


The heavy duty class is reserved for biggest and most powerful trucks which are built for towing and commercial purposes. With enormous dimensions, heavy duty components, double rear wheels and towing capacity big enough to move continents, GMC Sierra 3500 HD is one tough and capable truck. Of course, there is no point of owning such capable vehicle if you are a regular driver but if you are doing construction work, towing big stuff, or just need pulling power, this is the truck for you.
