I LOVE mine. Love love love....
It is my daily driver and I am getting the same mileage listed here. I haven't had it that long, but according to my fuel gage, I am getting a little better mileage than my 1500 with mds.
As for trailering, I have a 7100 dry trailer and my wife packs 1 weeks worth of stuff for a two day trip. Our last outing, for the first time EVER, I hauled a FULL tank of water...it was so nice driving straight to the site....
The truck did GREAT
I can't remember if I mentioned it or not, but it love this truck.
