Best part of being on here is learning from others...thanks for the input!!
Here is a screen shot of what I used to set up the steering on the truck at full lock....maybe I did this wrong??

That CAD drawing of the truck turning is exactly what you want. Perfect, in fact! I think the problem is your steering drag links do not travel equally, nor in a parallel / linear fashion, if that makes sense. Take a look at this picture.
Because your center steering arm swings in a substantial arc, the drag links do not maintain much parallelism with each other. With the wheels turned to the left, the more steering throw you add, the more out of parallel the right side link becomes. The result is the right link pushes the right knuckle more than the left link pulls the left knuckle. The knuckle on the right is at a greater angle, which is exactly the opposite effect you are after. Does that make sense, or am I barking up the wrong tree?
