Secured to your trailer

Hey Dave,
I've been known to haul a few.
Why are you NOT using the hook in the pic I have circled?
It is designed to go into that slot with a twist and does not come out like that "S" hook you have in that slot could.
I was just wondering. I haven't been doing long and my tow truck buddy might have told me wrong.
Please advise and
Thanks, John.:glasses7:

John, you have a good eye. But that hole is made for an outbound pull. If I used the T-Hook, it would not stay in the slot . There is another T-Hook slot behind the suspension designed for an inbound pull and I would have the same problem. The slot is pointed in the wrong direction.
So I used the S-hook.
My trailer was set up to pull the Dart but I have used it to pull many other cars here at work.
