7% Grade
In July i went up the Green River Gorge on I-26 in North Carolina it's a 7% Grade. Coming from South Carolina. I was doing 3000 RPM at 40 MPH in the right side truck lane. My truck is a 2002 Dodge Ram...

According Wikipedia. It's a 6% grade. and in truth it's not all that bad. We go up it pretty easily with the 150, and the 6K TT, and a load of wood. We do 55 MPH, at 3500 RPM It's not nearly as bad as Black Mountain on I-40. Where we do 45 at 2900 RPM
