If you are happy with it then it is fine, the alignment is off by an inch, as you said the axle is over 1 inch. So that may make it track a little sideways, may not even be noticable, but could lead to premature tire wear, or possibly wear on the conrtrol arm bushings; from them being in a little of a bind. It is even possible(and probably the case) that as long as the front wheels point straight and the back wheels point straight(even though they are not in perfect alignment with each other) the truck will go straight. The most likely place it would be noticable would be in tight corners. If the axle is sitting 1 inch to the passenger side, going through a left handed turn would be more stable than going through a right turn, this is due to the wheel being farther out on that side and being similar to having some wider wheels. Like I said if you are happy, then keep on truckin...
