I find many of these replies hilarious. For 2019:
Ford F-150 bumper pull, no receiver, ALL are rated for 5000#.
Most with the 53B option, receiver & wiring, are rated at 7000# or slightly over.
Tow package 53A tow ratings are all over the place, engine, wheelbase, axle ratio, payload dependent.
Max Tow package 53C is the only package to include the Trailer Brake Controller (TBC), but it is available as a separate option.
Yes, payload rating is critically important. Separate subject.
The Ford F-150 forum is the place to find more information about your truck than you thought possible.
The factory TBC is a bargain for near $100. You do have to reprogram the truck with Forscan or have the dealer do it. That way you can use your dash display to monitor trailer functions.
