GMC Sierra 3500 Summary

The GMC Sierra 3500 is a great used pickup truck that offers plenty of cab and seating options. Production for this pickup ended in 2006 and evolved into the GMC Sierra 3500 HD, which offers more towing capacity. Considering its final year of production, the interior of this pickup won't have the convenience of modern infotainment or advanced driver assistance systems. However, for a worksite vehicle, the GMC Sierra 3500 is still impressive. Boasting heavy-duty towing and hauling capacity, this model is worth a test drive for those looking for a vehicle to tow a fifth-wheel trailer.
