(It was the highest ratio gears offered by ford so I may be off with that number)In 10th gear at 70mph, we both run the same engine rpm and we have the same gas mileage on the highway when not towing. Looking at Fords towing capacity his higher gear ratio is much lower than the same truck with 4:30 gearing so that will affect his future decision in buying an RV and determining which he can tow safely.It's not like the old days when 4:30 gearing had the engine running redline rpm's at 50 mph.</blockquote>
