I never understood why they restrict HDPP to the lower trims. I get the philosophy that the package is intended to maximize payload. But why shouldn't I be able to simply increase the payload of any trim I'd like? The current generation allowed it on Lariat so I am disappointed and perplexed to see that it maxes out on the 2021 at XLT 301A.HDPP with more option selection would be great. I'd kill for a Lariat Sport 5.5 with HDPP.
