pluckyew, what RPMs are you turning at 70MPH? And is your ride (with the Rancho shocks) comfortable for long trips on the freeway, with no load? Thanks.pluckyew said:last 350-mile tank fill got

General Motors says they are pursuing this goal. In the near future they plan to have Displacement on Demand in their V8s to improve highway mileage (fuel delivery to some of the cylinders will be cut off at highway speeds). And later in the decade they claim they will have hybrid drivetrains in their big pickups and SUVs. One thing you probably wont see in the future is a weight reduction in pickups and SUVs. Look at what happened to the 2004 F-150 and the 2004 Durango. They both gained 400-500 lbs over 2003. And when rear wheel steering becomes more affordable from Delphi, that will make the big vehicles even easier to maneuver and park.You'd think manufacturers would be pursuing this... obviously they're not. They keep making 15 mpg trucks, and we keep buying them.
