From what I've read the load leveling is just a rear sway bar, not ride height adjustment. This was a thing in previous years and some folks specifically prefer the non heavy duty suspension for the better ride of having the rear wheels more independent of one another.
Also I've gathered that CCD is required for 22s to make up for the slightly harsher ride of the short side walls on the big wheels. I personally would have preferred the 302a package without CCD because I want to do a lift with 33 in tires sort of like a timberline but there's no way to option a high-end limited that way. I'm pretty sure a lift with new shocks will delete the CCD with no error codes (possibly have to disable it with ForScan) but it's a shame that I have to pay for it then toss it.
