Open driver's door and locate this sticker. Note what you have where mine says 2051:
That is as equipped payload and includes all the options your exact vehicle has, but no people or driver. Take that number, subtract an estimated weight for your family and a few things to entertain them en route, and the rest can be used for trailer tongue weight. So, let's say you have 1500 pounds. Family is 600 pounds. That leaves 900 left for TW which is about a 7000 pound loaded TT. I bet you need to stay under about 6000 pounds dry.
The good news: Your 6.2L/6-spd trans will pull it very well.
