Help with Companion Pivot Arm position Please

Installing our new B & W Companion today. In the instructions I get 9 options for where to mount the Pivot arm for different vertical and horizontal positions. I can figure out the vertical placement so that we end up with a level trailer when towing and adequate clearance above the bed. However, do I want my Kingpin 3" behind the post, 5" behind the post, or 7" behind the post. We have an 8 foot bed, so I'm not concerned about clearing the cab, but do I want the kingpin closer to the cab or closer to the tailgate? What is the difference? Ride? Thanks in advance for the opinions.

    The king pin should be over the rear axle or slightly forward.

    Truck 'carries' the trailer pin weight. That weight is carried by rear axle/suspension/tires (very little weight will be transferred to front axle)

    Farther that weight is behind rear axle the more unloaded front axle will be.

    My B&W center line (pivot) is about 1" behind the axle center line and in the lowest set of holes.
    I am still slightly nose high but it tows just fine.

    My truck has a service body so mine is kind of a unique situation.
    We have towed the fifth many mils so I don't think any changes are required.
