Just got back from moving the Rig up to CT for the summer, the truck preformed flawlessly, the Virginia hills where no match for the DD Series 60. Spent a couple of nights at Truck Stops, truck stops are about the only place that makes my Rig look small. Did the $500 fill up once, it's such a pleasure to drive I don't mind. A few of the steep grades that have special right lanes for slow moving vehicles where not applicable for us.....did I mention I love my truck......LOL , class A drivers have no idea what they are missing.....have fun on the road....
