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!
This truck is very powerfull great for towing has a grade break for slowing when going downhill. It is loaded with options and is a very comfortable ride!
I have driven a lot of trucks including transports and have never liked a vehicle as much as I like this one. Low maintenance good mileage lots of power the only bad thing is that it came with a 26 gal. Fuel tank so I upgraded to a 52 gal tank at $3500. Which was a ridiculous price but in the end well worth it. Amazing truck would certainly buy it again. Carl
