Keep it up and you folks are going to coerce me into telling my full embarrassing story....
I do know that the runaway e-brake cable does work when connected to the receiver chains hook up place, but IMO it's better looped over the ball.
When my pod came off it did work, but it caught on the little wire flap things on the runaway chain and bent out that and pulled off and dragged on the road, but not before locking up the brakes thus saving the rpod (and my tailgate)-- all at about 15mph from six miles down the road from where I hooked up and then somehow drove at 65 mph into town with an unhooked hitch. Cripes. Duh.
It all screeched to a slow speed halt, thank you God, no damage save the bottom of the jack stand ground down a bit because I didn't have my chains crossed and tightened/twisted up properly. Learned that lesson in spades.
A nice pedestrian nearby ran over and we picked up the tongue and set it back on the ball and I rapidly escaped the ridicule that was no doubt occurring with the other observers.
The hitch on my pod has now done that to me three times since then, but it was always caught during my new hook up procedure.
I now always drop the trailer on the ball, hitch it up and then again raise the jack to see for sure if she's on. It better lift the pickup when I jack it up. And I now also grease the ball.
It's just a crappy cheap hitch compared to all the others I've used. Unlike the Bulldog hitch.
Three other times I found it should have been shut, it appeared safe, the pin went in and the clip went down, but then I could crank it up off of the ball. Too much paint on the new hitch is one cause, and frankly it's not a very good hitch.
A "friend" of mine used to sneak up and jerk on my gooseneck horse trailer runaway cable hitch when the opportunity presented itself as a joke to lock up the brakes and keep me behind him on the road.....
so be aware of that too. If your brakes are locked up check the pin on the runaway unit to see if some clown has tripped it.
I now loop the runaway over the ball , and have for several years with no problemo.
Happy travels.
