im still getting back use to towing with a 6 speed, some of the hills killed me and were user error. havent had a clutch in 2 years haha.
its pretty good. i was hopping for more power, but its 20mph faster on big hills than the 4300, and holds medium hills with cruse at 67 fine.
dissapointed half a tank of DEF only lasted 1300 miles.
we figured 29k lbs and 8 mpg this weekend
