Add one to enhance towing experience

I'll go against the go-ahead-and-pull-a-fifth-wheel-with-a-Yugo-even-though-you've-never-towed-anything-in-your-life cops grain and say that a WDH may not be necessary but it is a good idea. You asked what will ENHANCE the towing experience. While a WDH *with integrated sway control* might not be required equipment, depending on the trailer you get, it will help by reducing rear end squat, front end rise, porpoising, push-pull from large vehicles as they pass, and any external source of trailer sway that could otherwise ruin your day.

It will ENHANCE your towing experience. Everything else mentioned is required equipment if you want to connect the truck to the trailer, and have the transmission last longer than halfway through the first trip.
