If the truck has a steady pull the caster is not right. Caster changes as the suspension moves. It's possible the caster could make the truck have a small amount of bump steer.

Toe out will make the front end dart around as it goes over small bumps, or changes in road crown. Toe in make the front slower to respond to steering inputs and bumps.

I have worked with suspensions that had so much bumbsteer that the tires will skid as the suspension moves, but the truck still drives straight thru bumps. The truck would leave skid marks from the bump, but felt just fine to drive. (This was a 2000 up 2wd 2500HD with a Fabtech 3" lift spindle. The spindle was designed for a 2500 and retrofit onto the 2500HD)
