I picked up a 2006 Titan SE model a few months ago which I bought to tow my 26'boat weighing in around 7000lbs. Question is the truck did not come with a hitch so I had one added at a local shop. I had asked the dealer what difference was between what I bought and a truck with the tow package and stated the biggest difference was the rear end. I was told if I was pulling short distances that I would be fine and he indicated that I could go up to 9500lbs. The manual states 7400 without the tow package. Did I get screwed or will this thing really pull 9500lb ??
