dog wagging the tail

I apologize for not telling my chassis.It is a p30/32 chassis,92 model.I had all kinds of things done to the front but not much to the rear.I had all steering components checked for tolerance,greased all points,new air bags in the coil springs installed,tie rods,supersteer bell crank on driver side,checked gear box,changed steering pump.I had three alighnments each time adding more caster using supersteer bellcrank specs.I made sure the coach set level from front to rear with no sagging.replaced cracked bushings in the front sway bar,Rear ones are fine per tech.It has helped a little with the wander and a lot with the sway.I am gitting ready to get a second opinion on the steering component tolerance along with the gear box before I go the track bar route.the track bar is the only thing I haven't tried and that only because the tech that checked it out and did all the work said he didn't think it needed one but I think the rear extends far enough out it could be causing my problem.
