First bone-head mistake this past weekend.

I wonder if I had both sides chocked if it would have prevented this. As mentioned, the friction anti-sway was hanging down from the right side of the tongue and propped that side up. When lowered, the weight of the trailer caused the anti-sway device to push it left. Would the chocks hold? Something has to give. Maybe it would have just bent or broken the cotter pin holding it there.

Thanks for all the advice :) Not doing that again.
