To Brake assist or not to brake assist ?

I guess it is possible but I can't even imagine how a toad can break loose unless someone tried to cut corners. I mean you have to have both arms of the tow bar fail, as well as both tow chains, or perhaps your hitch broke loose and the entire tow bar came loose. In that case, you still have the two tow chains. I never trusted the hooks on the tow chains and I replaced the ends with screw on links. These will never come loose and will hold the vehicle if everything else fails. On my rig, I would have to have four things fail at once for my toad to break loose. This seems highly unlikely.
