I've got 3.92 gears on my Ram... and can cruise at 80mph's under 2300RPM's... So im not sure where your getting that from... My truck is much better on gas on the highway... I bet I could put it in cruise control at 90mph and still be under 3,000rpm's...
Hey kevin I've got your 3.92 auto gears... for about 3k... Make a deal?
