Suss6052's right. ;D
SkyPilot, It's not too bad. If you keep it to around 65mph, on a highway without a grade, you're spared the worst of it. Accelerating from 65mph to 75mph from 5th gear and you'll get a good dose of drone. I don't like to pass or speed up with 5th gear at all, just cruise, so it doesn't bother me too often. With this, it's keep your right foot light, or set the cruise to 65 and forget it. 3200-3300rpm seem to be where it's at the absolute worst.
