You could tow the "Rover" and the trailer and still not feal a thing behind the Duramax
. My buddy and myself towed 2 Jeeps on a 38 foot goose neck trailer tip the scales w/ 3 trucks trailer gear and our fat a$$'s at 26000 lbs and still got 10 mpg at 70+ mph!.If you need more power look at some of the chips they realy turn things up. Don't was the money on the Banks kit , to much $$ and not much more power for the extra cash. Enjoy the new truck.
