Average tongue weight of TTs is 12-13% of the gross weight of a TT (but can be 14-15% in some cases). Not knowing the actual weight of that particular TT, using the GVWR for a max, the TW will be 1100 - 1200 lbs. So, well over the TV payload max before even taking weight of passengers, pets, groceries, camping stuff, etc. into account.
You need either a shorter/lighter TT or a more capable tow vehicle. For longer TTs like a 34 footer, a TV with longer wheelbase helps too. We have a 3/4 ton truck with regular cab and long bed and it tows great with no sway and excellent handling. If the SUV is needed as a daily driver, a shorter/light TT will be required.
For TTs, the max payload capacity of the TV is the important number to watch and normally will be reached before the max tow capacity.
