My truck is a 2018, and the list on post #28, doesn't list my truck as available with HPP... but it has it. It's probably due to MaxTow, but also have the optional 3.5EB, FX4, etc., so not sure which package was actually responsible for getting an HPP frame. Strangely, single-cab trucks with the 141" wheelbase can have an HPP frame, which I didn't know. So definitely you cannot rely on that chart, folks.
There are some other threads that deal with this as well. As other have said, Ford is not clear on what configuration gets what frame, and it doesn't seem super consistent. My SCrew 5.0 and regular tow package has the HD frame. There is a sticker under the cab on the passenger side on the trucks that show the frame code, if you want to check it on a truck you are considering buying. Here is a cheat sheet I found a couple of years ago (somewhere on this forum), that covered 2018 model year. I can't say if that is still valid, but may be. Still doesn't tell you which truck would get which frame, but maybe a little helpful. I noticed Bisonp's link above is to the other thread that had this image.
Yeah, I think most of us on the previous thread determined that this chart was inconsistent, but that is a Ford document, and the only thing anyone could find that gave any indication of what configurations the different frames were offered with.
Thanks for posting that pic. First 145" HPP frame sticker I've seen. My 145" SCAB, 4X4, 3.73 with 9.75" diff, tow package, lariat, 5.0 has the HP frame.
I suspect some of the "abnormalities" have to do with supply chain issues... there's likely no difference in the frames besides some minor thickness changes, so if they don't have any HDs on hand, perhaps they just build it with an HPP.
I know my maxed-out 157" SCrew 4x4, 3.5EB, 3.5, Max Tow, 502A, with basically every option only has the HD frame... whereas people have posted on here trucks that are lighter/less optioned/not MaxTow, but they got the HPP.
