At 60 mph I'm a little over 2000 rpms. I have never got my truck up to 3000 rpms, it defuels before that. Fastest my truck ever went was 85 or 87 at about 2850 or 2900 rpms ... and at that speed your hanging on for dear life (at least in my truck you are when driving that fast).
Fastest crusing speed for me is 75 mph at about 2500-2550 rpms.
