[Physics]Forklift Problem.

I have a forklift model set up to work as a car and I want the fork to throw things. I have this working but every way I try gives me different but unsatisfactory result.The fork is moved by animation and is a child of the car.

Animate Physics + Kinematic rigidbody = Flips truck when animated;

Animate Physics = Flips truck and target;

no Animate physics + Kinematic rigidbody = stable but inconsistent throw;

Have I missed the good way to do it? Thanks Maurice,
