Short Answer: Not even in the ball park of recommendation. You will likely exceed at least 3 of your Expy's ratings.
That will be 8500 pounds loaded for a long weekend with a family's gear. That will be 1000-1100 pounds of loaded tongue weight - exceeding the receiver rating.
1000 pounds of TW is taken away from available payload (check that Tire and Loading Sticker on driver's door) leaves how for people and some travel gear inside?
This is your first RV as well. Towing a TT is hard work for any TV. It's the largest/longest TT for the weight. An 8k boat will tow better than a 6k TT. Frontal area and side profile catch every direction of wind.
6000 pounds is a good number for the most capable half tons to keep the driver comfortable, and therefore the whole family to have a pleasant RVing experience. People that get over 7k dry tend to make changes very quickly, smaller trailer, more capable TV.
