ROFLMAO, post of the week!
(And I'd call bullchit on the Ram Mafia or Bowtie wearin folks just the same for a claim like that.)
Not to disparage the claim, it could be totally accurate, under the right set of circumstances....downhill, believing the computer generated mileage (it may be right though), tailwind and hypermiling at the same time or drafting a slow moving semi all come to mind.
It does not speak for the "average" mileage for "normal" driving though. No magic potion under the hood of the Superdoody or any other truck for that fact.
