I know. I'd be running 2300 rpm at 70 mph. Right now I'm at 1900. I'm not sure if that's too high or not. I'm also looking at running 3200 rpm at 70 with OD off while towing. Right now I run around 2700 and I think I need a little more but not sure if 3200 is too much. Anyone out there ran 4.56 gears with 33's? If so is it too much? I'm towing probably 60% of the miles I drive.
