Your X-terra does have cams for caster and camber and should be fully adjustable (within reason). They're always rusted solid up here, but I doubt that's the issue given your location. I accept under 0.4 degrees of cross caster/camber for my own work.
To help visualize, negative camber is when the top of the tire leans to the center of the vehicle. Positive camber is the opposite. The more positive value on the FR can cause a pull to the right.
You could also have a tire pull, even with new tires. Typically the car will track fine until you let go of the wheel. Crossing tires side to side should fix it. Dragging brakes can also cause a pull.
