I would think that a rig weighing 15,000 lbs would have brakes. You would need a good brake control unit on your truck if it didn't already come with one in the "towing package."I just bought a GD 5th wheel, gross weight weight 15000 lbs. I will tow with a 2022 Ford 2500 with their 5th wheel towing package. Will I need brakes installed on my 5th wheel?
