Front Wheel Alignment for 4WD

Are there any gurus out there who know how to decipher the Vehicle Models in the online 2005/2006 Repair Manual that deals with Front Wheel Alignment for 4WD.

For example, my tire size is P245/75R16 but I don’t know which spec applies to my vehicle; that is, I don't know how to determine my vehicle model.

In addition, can someone explain what page SP-12 is attempting to illustrate with regard to turning the cams. It would be nice to know what an alignment tech is up to down there.

 

I finally found my Tacoma's Vehicle Model #. It's located on the label inside the driver's door. In my case it is TRN240L-TRMDKA.

According to the 05/06 online manual, the Camber should be .58* and the Caster should be 1.73* See: http://i.minus.com/ibfdfStC9eO0IS.png

According the Chilton, the Camber should be 1.62* and the Caster should be .3* See: http://i.minus.com/irFKi2kTi1Ptq.png

Who ya gonna believe?
