If your thinking of buying a new Super Duty

I'm all for aluminum... Owned a galvanized boat trailer that was used in saltwater that lasted about 6 years and was toast during a time when most all boat trailers were fabricated out of galvanized steel. Today I currently own an aluminum boat trailer that's used in the salt that's 12 years old and the only parts ever replaced where the axles and leaf springs again galvanized parts. I would estimate that all saltwater boats sold today comes on a aluminum trailer simply because they last.

Also owned a 98 F150 that I sold after 7 years 150k miles with no issues on it's aluminum hood. I still see this truck ~1/year and it still has the original hood/paint with no issues after 17 years and over 350k miles.
