I am not convinced that the emergency break-away cable needs to be shorter than the chains. If the chains are working, then the trailer will follow the tow vehicle to a (hopefully) controlled stop. I would think that only when the trailer is completely loose from the TV should the emergency braking system be engaged.
Y'all convince me otherwise.
The last 2 trailers with brakes that I have pulled have both had the emergency braking system cable longer than the safety chains. If y'all convince me that the cable needs to be shorter, then that is another project that I need to tackle.
