I have been hauling my 2000lb RC trailer since I bought the truck with no drama. I just got back from towing my wifes Jeep to the 14th annual VA four wheel drive association Oakridge run and had a great time, both at the park and towing with the truck. Averaged 15 MPG and it only shifted out of overdrive once. And I think that was because I was only going 55. So much easier than my 94 Chevy 2500 gasser. The Chevy had drama at every hill or overpass and got 9-10 MPG. I still can't wipe the grin off my face.
