We looked and went through both TT at a show and liked them both and asked a lot of questions, the cherokee was the winner. The reason why the tongue weight is more is because the wheels are set back a little further than the grey wolf. (Helps it pull straighter, less bounce.). We tow our cherokee with a 2010 jeep commander with the 5.7l and it follows us very nice, i wouldn't climb Mount Everest, but it does great in the hills and valleys where we live. I needed to install firestone ride rite airbags in the rear springs to help keep the rear from squatting too much ($100) and an hours work. (They are fantastic, not meant for overloading, just for stiffening the springs when towing.). What it comes down to is which one do YOU like more.
