Rpm @ 72 mph was ~1500.
I guess I would question the gearing. Seems pretty high? Assuming it develops peak torque at 1600 RPM, at 65 MPH (highway speeds) it would be below peak torque. Not a problem for non towing. But if towing medium/heavy (say 14,000 LBS), do you think it would be shifting a lot when encountering slight grades at 65MPH?
I would think a bit lower gear might be better for heavey towing.
