Jump and run like a girl (no offense to the actual girls)

My old shop teacher had that happen to him while loading a car so he used to preach his experience to the younger people.

By not using the E brake or wheel chocks with any automatic transmission, you're putting a LOT of weight and tension on that little bitty parking pawl which isn't very big or strong.

A truck that new, 99 % chance it has an auto and same odds it broke the pawl.

Use wheel chocks, even on level ground because you gotta pull the whole transmission and tear it down almost completely to replace the pawl
