Place the receiver as far in as you can. That will allow less lift to the front of the tv by reducing the length of the receiver bar into the fulcrum point (the hitch).
In other words use the hole closest to the ball on the receiver bar if that doesn't interfere with your tv or proper towing. Move to the next hold back if it does.
