First real test of the truck was today on my maintenance route. It pulled the trailer awesome, its a lot smoother than my gasser was.
Things I don't like: The tailgate has that dumb curve to it and when I lower it, it hits the jaclk on the trailer. It will probably do it with all my trailers. The tow/haul button isn't on the shifter, its under the radio. I don't love the mirrors but I'm sure I will get used to them.
Other than that, it is awesome, the brake controller it came with is a ton better than the last one I had to install in my 2500.
