There are multiple fore and aft adjustments that can be accomplished with the Andersen. This enables adaptation to various combinations of rear axle placement and pinbox design. This is the list I can think of:
1 - You can flip the king pin adapter block so the ball is closer to the trailer, this moves the trailer 8" closer to the cab than if it's installed with the ball in front of the king pin. The advantage for this is that it changes the pivot point of the pinbox and places more of it inside the truck bed rails.
2 - You can use the Curt 4" Ball Extender to move the in-bed ball 4" closer to the tailgate. In combination with 1. above, this makes the trailer only 4" closer instead of 8".
3 - In some scenarios where the truck is a long bed, Andersen approves installing the pyramid frame backwards. This moves the pivot point closer to the tailgate.
And all of these three can be combined with various pin box scenarios, i.e. Extended Style Pin Box etc.
Of note is that for most Andersen users, none of these are required. Usually, the standard installation provides enough clearance to avoid the need for a slider but it's nice to know that when you get around to installing, if something isn't the way you expected, you can adjust.
