The adaptor can be installed either with the kingpin in front of the adapter's ball hole or behind the ball hole. This has the effect of moving the trailer nose either forward of the top-of-Andersen ball or behind it.
Separately, the Reese or B&W GB extension moves the bed ball 4" towards the tailgate.
For maximum distance from the truck cab, one could use the GB Extension (4" toward the tailgate) PLUS mount the Andersen Adapter with GB socket in front of the king Pin (8" from GB hole to King Pin insert). This combo puts the kingpin 12" back.
If the king box is having issues with bed rail clearance (i.e. truck is too tall), one can choose to move the pivot point and thus have the entire kingbox rotate within the truck bed walls (obviously this is dependent on which kingbox, but it worked for my LCI 1621 compatible). The trick here is to use the GB Extension bedball (4" toward the tailgate) and then REVERSE the normal Andersen adapter mount to have the GB hole BEHIND the kingpin (this moves the trailer 8" toward the truck cab). The net is only a 4" move of the trailer nose toward the cab.(8" minus 4").
This demonstrates the nice adaptability of the Andersen Ultimate hitch. The hitch ball is adjustable up or down from 13" to 19" off bed floor. The above mentioned mounts provide enough forward backward selection that for most of us, no slider is required.
There are 2 other mount possibilities but the two mentioned so far seem to be the most popular.
PS. I've towed my 11,000# trailer 12,800 miles from California to Florida, Texas to Wisconsin in the last 14 months. Trailer and truck tow level (even with my airbags deflated to the minimum 5#). I've made probably 3 or 4 almost 90deg. backins into tight Arizona resort style pack-em-ins with no issues. I continue to be a recommender of this hitch. See my sig for truck etc details.
