Just got back from a 1300 mile round trip this weekend to Colorado Springs and back home to the KC area. Truck ran great, but those horrible roads on highway 24 would have been much nicer with better shocks. 17 mpg round trip with the 6.2 liter. Bed was full with gear, we had 4 bikes hanging off the back bike rack, and 5 adults in the truck. Drove up pikes peak highway and the truck didn't skip a beat. On the way down I shifted to low gear and my brakes were 205 degrees at the brake check station which was perfect.
