I’m doing this off the top of my heAd so some of the numbers may not be exact. If you order the 6.2L performance pack you get the magnetic ride control. The suspension is actually softer. The front springs for from 610 lbs per square inch to 560. The rears go from a 250/445 progressive spring to a 245. We have a 5.3L RST and am actually surprised at the ride quality without the mrc. 22s can do very bad things to ride quality.
Re the tow package. If you have the 6.2L and the 10speed the rear gears are 3.23s regardless if you order the tow package. Only the 5.3L goes from 3.08s to 3.45s, a 12% increase in to multiplication.
