No one here can answer that question for you. Only you can provide the real time info to figure out the answer. It's purely a math questions.
You need to look at the "payload" rating for your truck, it is on the yellow sticker on the door. It will say something like "Gross weight of occupants and cargo should not exceed __________ lbs." That is the number you need to start with to determine how big a TT you can tow. Once you have that number, you calculate all other loads in the truck like how much you the wife and kids weigh, how much you may be carrying in the truck bed (toolbox, firewood, etc.), plus the loaded tongue weight of the trailer and you get your answer.
