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...
Yes that sounds right. As you drop to 25/30 mph you will be shifting to first gear. The real fun is when you continue losing speed in low gear ;) Holding RPM at 3000/3500 is the correct zone for your truck when max climbing.
