My truck is kida jittery on the road and you are always paying attention when driving it or else ! Toe is at 0 and it has a new stabiliser . Still a 2 hander tho .

Caster and camber are two different alignment angles. camber is predetermined at the factory and is not adjustable.

caster is the angle of an imaginary line drawn through the center of the knuckle steering pivots compared to a line 90* from perfect level as viewed from the side. kingpin 60s seem to like 3-6* of positive caster(leaned towards the back of the vehicle at the top) so the line drawn through the steering pivots when looking at the drivers side is like this /

if it is wandering it probably needs a little more positive caster. and a smidge of toe in. measure the caster with the truck sitting as level as possible and loaded as it would be normally. then measure the angle of the top of the steering knuckle flat where the steering arm or spring cap is. you can usually get a close enough reading off the bolt heads for the spring cap, but using the top of the studs on the arm is sketch because they may not be threaded in the same amount.
