Funny, I don't carry a cell phone either. I only will if I'm on a trip somewhere. I took the truck out early this morning and got out on the interstate. I don't know how fast I was going because my speedo is broken and my daughter has the GPS. But I'd guess between 60-65. Everyone was passing me. But the truck felt like it was running smooth and there was no noise or vibration and the temp stayed nice and steady. I could probably do the whole trip on the interstate but like you said, the scenery is a big draw. I95 up the east coast is boring (when it isn't plain old nasty).
