Highway, Speed & RPM's

Not sure of my rearend gears, but at my normal 85-90mph highway speed I'm spinning about 2700-2850RPMs for over 100miles. Is this normal? Should I drop my speed a bit? Thanks.

Heck dude?! Try to maintain just over 3000 RPMs. You'll get there sooner and the truck will have time to rest!

These ENGINES were designed to run wide open all day long.
