Did your other trucks have same wheelbase, were they also 3/4 tons? The longer the truck the longer the turning radius given same front axle and steering stuff.
When you turn it hard one way or the other what limits the wheel cut? Are the spindle stops on the axle there as original or installed wrong, adjusted wrong if adjustable?
On my 1 tons I always thought they turned quite nice. Even with larger tires that at max turn just wanted to rub the back of the front springs.
If your tires are close to rubbing the springs as max turn that's best you can do. Assuming original type and size wheels and not aftermarket ones extra wide or with to much inset.
