About to buy a TT, so confused, could use some help.

You will be over the capabilities of that SUV. Having towed an 8,300 lb trailer with a Tundra I wouldn't do it. My dry weight was about 7,200 lbs, plus gear put me at a CAT scale weight of just under 8,300 (no water in tanks). So figure 1,000-1,100 minimum once it's loaded.
