Let me share a story with you.
When I bought my 39 ft DP, i also bought a 2006 Wrangler for a toad. I installed a braking system for it, to include breakaway.
One day it paid for itself. I was distracted by my wife in the back and did not immediately notice that the traffic in front of me was stopped.
I took both feet and stomped on the brake pedal with all my strength. the anti skid could be felt cycling. I could see that the toad system was working by the red light that indicates it is on. I stopped with about 10 ft to spare.
Had I not had the additional braking, I have no doubt that I would have hit the stopped traffic.
Do you need brakes? How lucky do you feel?
