I have a 2010 CC SE non-big tow. As far as I know the only difference between the big-tow and non big tow are the gears. Is that right? So my question is what can I realistically and comfortably tow with my Titan? Door panel says somewhere around 7000lbs if I remember correctly. I was at a camper show recently and I'd like to get an idea of what sort of dry weight and tongue weight I should be looking at. My first guess is somewhere around 6000lb dry weight. What do you think?
