Short answer, I would not recommend Towing any one of those with the Armada. You will run out of payload with the Armada long before you exceed the lbs it is rated to pull. Tongue weight on a TT will be 13% or so of its loaded weight. A 6500 lb TT once loaded will weigh about 8000 lbs meaning it will have about a 1000 lb tongue weight. Add 100 lb hitch, 300lbs gear in the bed, 500 lbs passengers in the cab, the truck will be overloaded and you will likely not have a desirable Towing experience.
I would stick to a trailer fully loaded not exceeding 6500 with your truck.
Find out what the payload rating is for your truck (my guess is around 1200 but the sticker in the door jamb should tell you gvwr) and take it to a scale. You will then be able to determine how many pounds you can safely add to the truck including the trailer tongue, hitch, passengers, fuel, gear, etc.
For any of the trailers you mentioned, I would recommend a 3/4 ton truck and a good WD hitch set up.
