Happijac tiedown system and the new Ford Aluminum beds

I had them many years ago on my 94 Dodge carrying a Bigfoot 10.6. Installed per directions they cracked the sheet metal where they attach. Later they came out with a backer that addressed the situation. I assume that the product has improved since 1994. Since then I have gone with frame mounts and never had an issue. Have you contacted Ford and asked?
