I finally have a good recent kill story!! Today I was coming back from a camping trip in the White mountains of Arizona pulling a 35' fith wheel with my '08 6.4 on Hwy 60 between Show Low Arizona and the Salt River Canyon. Well I was just easying along about 65mph when I came to a hill that had a passing lane, I pulled over so people could pass me and looked in my mirror to see about a '04 or newer Duramax coming on about even with my bed smoking quite a bit!! I just could not resist so I laid the hammer down and easily pulled away from him topping the hill at almost 80mph!! He got right on my butt on the other side of the hill but fell way behind on every hill smoking quite a bit!! Here is the kicker, he only had a single axle flatbed trailer with a couch on it! Maybe there was something wrong with it, but it would roll some coal, any way it made my day!
