My bets on cylinder deactivation, and dammit, I'd bet my left nut that even a full size truck could get ~35mpg at 55mph w/ the Phil Knox aero treatment, LRR tires, and some way to manually actuate the cylinder deactivation doohickey.

My 2008 Chevy Tahoe has the Eaton Active Fuel Management system (internally called "Displacement on Demand"). After 24k miles, and using the ecm provided instant fuel economy, I can see the change from 18 to 26 mpg on a flat road at 55 mph very day, both directions. This includes trailer towing(boat and hay delivery).
