The toad has to be straight so the pins don't bind.
I found if you are caught where the toad is not straight turning the wheel will unbind them.
After I was directed into the wrong CG site during the night that left me with a concrete parking bumper in front of my MH and my toad at a sharp 45 degree angle I had to find a way to get those now really jammed pins out to get the toad off so I could get the MH out. :R
A small hammer and a small socket extension fits just right to tap the pins out in a situation when all else will not work. That combo sits under the seat of the toad at all times.
