For the actual max TT weight you could safely tow, use the lower of GVWR, payload, or hitch rating.
Check the Tire and Loading sticker on your door jamb for actual cargo carrying capacity(payload). Subtract the weight of all passengers, cargo, and hitch.
Adjust the numbers as needed:
1446# max payload - 600# passengers & cargo & hitch = 846# payload left for TT tongue weight.
846 / .13(13% tongue weight) = 6507 # max loaded trailer weight.
If the GVWR is 5800lb, then that would be the maximum TT weight.
Check the hitch receiver for it's capacity(3400 or 5400?). If it is less than the others, then the limiting factor is the hitch.
Also keep in mind the horsepower/torque and a longer wheelbase will determine how easy the towing experience is.
