Ford truck and suv frames

2021:
Type: Thickness / Section Modulus
LD: .087 - 4.726
HD: .094 - 5.14
HPP: .102 - 5.55
HPP: .11 - 5.96 (164.1 WB only)

2020:
Type: Thickness / Section Modulus
LD: .087 - 4.95
HD: .1 - 5.73
HPP: .11 - 6.28

My assumption is that HDPP would get the HPP, though I have seen some max tows get both HD and HPP in previous years. Don't know if this was due to parts on hand or if it is impacted by some options. I wonder if if normal Tow Package gets HD or HPP. Could people post their frame stickers for 2021 with the specs of their truck?

Edit: Did a lot of busy work:

I work in quality for a company that manufactures Ford truck and sub frames. If there is anything I can help with plz feel free to contact me. Thanks everyone 🙏

Well I will!

I get that there's a sticker and a part, that should match,

Where is the best place to measure thickness?
(No, say, hole punch deformation, or no hydro-form thinning near a curve.)
