So this weekend was opening weekend for dove season, so the men of the family take a 4.5 drive to south texas near mexico. Naturally at age 16 I can't stand to drive at 60mph, cause everyone else is 70-80mph. My question is.. is it too tough on the truck to run it at 75-80mph at 2100-2300-RPM's constantly??? the truck acts like it's really wound up. Just curious if i'm damaging my truck or not.
