You know, last summer my brother left on vacation with his 5th wheel from here in southern MN. He got as far as Nebraska and decided that his 5th wheel was not going to make it so he stopped at a dealer and bought a new one.
As they were hooking it up to his truck the dealer saw the Break Away Cable and said "You don't need this" then he rolled it up and zip tied it under the hitch. lol
My brother towed that 5th wheel all over the West without the cable being hooked up.
This year I helped him hook it up before he left on vacation.
