If you're going to be hauling a trailer much at all, PLEASE break down and buy an electronic proportional controller... I use the Teconsha Voyager in my truck (95 half-ton). It works GREAT (slows down my truck and gooseneck stock trailer, 11,420lbs), costs very little, and lasts forever (mines at least 12 years old, and my dad's is older yet....) It's small and unobtrusive, and can be pretty well hidden if necessary so as not to detract from the looks of your truck.
