This is my trip up north, up and down hills. I know there must be some really good ones out there but, I didn't try very hard and was moving pretty good for Ontario roads.
750 mile round trip...from the valley floor through the mountains at 6k feet and driving about 200 miles on dirt roads looking at hunting spots....2015 Laramie ccsb 3.55 gears with gear ice chests and three guys
Also air ride and ram boxes....believe it or not the "aero" mode on the air ride going down the hwy makes about a 1mpg difference by dipping the nose of the truck...but does make for a bit bumper of a ride
