I recently drove my 2001 F-150 SuperCrew ~85 mph for about 5 hours straight. Obviously it wasn't completely non-stop at that constant speed, but that was where my cruise was set and what I never went above while driving. I was simply wondering if there are any adverse long-term effects of driving fairly fast for a long time. It was only at about 2400 rpm the majority of the time, so the truck wasn't wound extremely tight the whole trip. Anything really wrong with it (besides the fact that I was speeding, which I'm well aware of)?
