Sorry but gotta jump in here, to much mis-information.
Caster is always a concern, especially on a lifted truck with large tires. If your caster is not set properly the truck will wander all over the place. The problem with setting caster is the more caster you set the worse the pinion angle. But caster is more important than pinion angle so set it where it drives best. Or do a cut and turn, but most aren't going to those lengths.
Second point, camber does not effect the steering returning to center. Steering return to center is effected by caster angle. If you caster angle is to low, it will not return to center and wander. Again, proper caster angle is very important to get your truck to drive as best as possible.
