Correct Track is something of a gimmick in my opinion. It will only adjust one part of the alignment, tracking, or how how square the tires are with the frame and each other. When I buy my next trailer it will go directly to a heavy truck alignment shop. There they can adjust tracking, toe and camber and probably for the same amount of money an RV dealer will charge to adjust the Correct Track. Trailers are not aligned when they are built and they will only be as good as the person that welded up the spring hangers and axles...I rest my case....Don
