lol either you changed the first post significantly or I was clearly out of it yesterday ha
This looks to be a 3rd party warranty FYI, despite it being offered by a dealer. If you truly believe you will own the truck for such an extensive period, I could see a benefit, but id worry of limiting coverage so far down the line, plus extra hassles in the warranty claims process as opposed to a true ford warranty.
An official Ford premiumcare warranty plan can be had quite cheap online (less than half that for ~6-7yr100k). A major benefit to ford coverage, if you trade in or sell truck your truck, you will get a prorated refund of the cost back. You can also transfer it to the new owner, so it adds resale value too.
Realistically, most people will sell their truck before reaping the rewards of such a long warranty, so I'd look into its transfer-ability and or prorated refund options, which Id think are unlikely to exist
