Do we need another brake system ??

The crux of the counter point for me is this; There are no laws governing stopping ability. A few states have laws based on weight and supplimental systems but none speak to the distance in which a MH must be able to stop. We could all improve our braking distance. But I would bet dollars to donuts I can stop quicker and shorter in my small, light class A gasser with a car on a dolly without brakes than a lot of larger Dp's with toads with supplimental brakes. Point being - as many have pointed out - each person's scenario is different. Know the laws and know your equipment. Let me be clear, I think anything to err on the side of caution is a good idea. Supplimental brakes are a good idea. But some do not need, or are not mandated to have them. And some that do have them still can't stop in a safe distance. Of course one would need to define safe distance. Many have them and have issues. Many don't have them and don't crash into everyone or unleash fire and brimstone. Stick to the law, your comfort level and common sense driving habits.
