With all due respect I pulled that bastard ALL over creation with never a problem. The brakes on that Airstream were monsters and could slam you into the windshield, esp. if you apply manual pressure to the brake controller, within reason. In spite of this I never
had a problem with the breakaway cable nor the pin can. I always maintained it before a trip by manually pulling it out to ascertain hearing those lovely magnets clamp down on all four...also kept it clean, lubed, and covered when parked! Keep it clean as many people never check them.
To re-state what I said previously...I simply slipped the cable loop at the end of the breakaway cable over the inserted
hitch pin end, and then attached
the spring cotter pin after
that as per normal. NO
caribiner involved...made sure the cable didn't drag ground nor hang up in any kind of turn, foward or
backing. AND...if the hitch ever gives way...I guarantee that the drag weight of the hitch and\or WDH(bars) will cause that rascal to activate and lock wheels! Just make sure the switch activates as it should and give the cable
a little breathing room when routing it from the can to the pin(or whatever...). I always crossed my chains and attached them to the holes on the Reese made specifically for that purpose. Be safe...happy trailering!
PS: I've never seen a failed hitch that was professionally installed, have you? Though I'm sure it's happened in the past...nothing is impossible...right?
Look closely at kandl's set-up above...that's what I'm talking about!
