1999 Dodge Ram 1500 4x4 5.9L. All the brakes and rotors/drums are good. Like I said previously without pulling the boat it stops on a dime like it should.
The brakes on Dodge trucks SUCK. I had a Dodge Ram 1500 for a few years and experienced the same thing as you. I recently got rid of that truck and bought a used GMC, now I barely notice that I'm pulling a boat.
