I have owned a Dodge Cummins and this 2006 GMC

2006 Duramax is great truck for pulling my travel trailer. When just the truck over 20 mpg and 13 pulling a 8,000 trailer. Very comfortable and stable on the road, plenty of power. I installed a Pioneer system with 7" screen, blue tooth, dvd, satellite radio and android auto. With that I have every option of a new truck except the collision avoidance and lane change type items. Great performance!
