Considering this TT 23' Passport Elite Weighs 4747 dry guessing around 6K lbs set up to go. TV; '17 Ford F-150 with the 5.0, 3:55 rear gear and tow package. Equilizer hitch. Truck rated for 9,600Lbs. ...
I'm sure you will be fine, those numbers are well within the capabilities of that truck. The 5.0 is a great engine and you have a light trailer and are packing relatively light. I'd suggest a good WDH, I like the Equalizer. Not sure what tires you have on the F150, but I would encourage you to consider some LT tires, load range D or E for stiffer sidewalls. That will certainly help the truck feel more planted.
