After getting the breakaway-switch cable caught in our fifth-wheel hitch and pulling the pin (and hearing of the same thing happening to other RVers), I came up with an idea to help eliminate the potential problem.
I purchased a length of clear tubing at the hardware store that is about a foot shorter than the cable and started feeding the cable through it. After the cable was pulled partway into the tubing, I put a key ring at each end of the cable loop to ensure the tubing won’t fall off the cable. Now it will be very difficult for the cable to get caught in the hitch and put the brakes on the trailer.
