I also have the US Gear Unified supplemental brake system on my toad. As long as the driver kept his foot on the rv's brake, it would have activated the toad's brakes keeping it at max distance (as far as the single arm o the tow bar would allow) and not allowing it to slam into the back of the rv. Obviously, the driver must have taken his foot off of the brake momentarily allowing the toad to free wheel and run into the back of the rv.
Constant pressure on the brake would have prevented this. OR.... he could have reach down to the supplemental brake controllers and activated the toad's brakes independently of the rv. This too would have kept the toad from hitting the rv.
In a super high stress situation, remembering to do this is understandably difficult. That's why I occasionally will "practice" this action and hopefully I will remember .... yeah, right.
