Of course I have a brake controller, a prodigy p3.
The truck has a "towing" capacity of 8250 as equipped. which means 4400lb trailer with 3200lb car make 7600 lbs and since dont weigh 650lbs i would assume im good, and as far as brakes, i would be willing to bet my 1500 has much bigger brakes than anyones 2500 from more than 4 or 5 years ago....
