What we do is make a full size map of all the 4 link mount holes at ride height wet with tire pressure set. Then we draw the lines through the holes and make a spread sheet of the hole locations and combinations with there associated lengths and heights. Then pick a starting point based on the vehicle and power. So for your truck I would build a base line sheet that included four link and shock settings. Sheet would look like this
Four link 47 1/2" out 8" up
Preload neutral with driver and no anti roll (set with top right bar)
Rear shocks compression 2 clicks from dead soft, rebound in the middle of the settings.
Front shocks 3 from dead soft.
Tire pressure 8 pounds.
First runs would be with out anti roll to see if any preload is needed to get to track strait in water and the leave.
Then we would make passes and take notes and make adjustments based on video of the leave.
