Yes, that is always a risk and why you need a braking system in the Braptor and have to drive defensively. I towed a 2019 Jeep Wrangler (about 1,000 lbs lighter?) all over without problems. The F450 has strong brakes and diesel engine braking but I accept your words of caution. My tow bar is about one inch lower in front where it connects to the F450 and the front end of the Braptor should drop with heavy braking.
For rear lights on the Braptor , I custom made a separate sub harness attached to the frame and attach a light bar to the spare tire. And I use a separate 12 vo!t power cable to the braking system direct from the battery.
