tow vehicle

It is safe to say that any working supplemental braking system will stop the combined motorhome and towed vehicle in a shorter distance no matter the size of the rigs. I think that is safe to say that whatever that reduction, it is only important if that extra distance would have prevented a collision which could result in serious damage, injury or death in that particular instance and that really is the bottom line. Will you ever be in that situation??, probably not, but if you are the unfortunate one to have it happen to you then you will realize that all the rationalization in the world means nothing.
