If you would have had caster set more positive it would have never happened again. The reason it happens on the newer trucks with few miles is because when a truck runs down the line and is aligned, its not very precise. This is why some trucks can have an issue with DW, and others don't. Big tires and lower air pressures can accelerate the problem, but don't cause it.
