I tow a 35ft TT with a V-10 X with 4.30 gears and i have the 11,500 lb tow rating. The V10 X's had an 8900lb tow rating while the diesel has a 9100 or 9200 lb GVWR. Not sure on a 2WD diesel X. The 02 receiver has a 1250/12,500 lb weight rating. It was upgraded from 01 with nothing more than larger hardware. I can tell you i am at my trucks max GVWR, but you would never know it maybe even a couple hundred over. With 4 kids they will be over the X's GVWR, but i would not be concerned with going upwards of 9500lbs. The limiting factor will be the weak rear springs. Everyone that has an X does something with the rear suspension, air bags, F250/350 springs and a rear sway bar.
I've had my setup for well over 15k towing miles with no issues. The biggest key is proper hitch setup and a good sway control system. I like the dual cam system. As you can see it has worked great for me!
