It would help a lot if you post exactly what you TV is. But the GVWR is the absolute max the TV can weigh fully loaded with everyone and everything in it, including the hitch weigh of the TT. But don’t use that number in your search for a TT, pulling at or near your max rating will not be a fun experience. There are a number of rating for your TV and you need to meet the "weakest" one. And put little stock in the GCVWR, you'll likely exceed some rating before you ever reach that. And never believe what a salesman tells you what your vehicle is cabable of pulling, instead ask on the forum.
