Problem solved! But then they'll call me "Slow Lane Charlie".
Back in the days of 55-65 mph speed limits, I put several thousand freeway miles on the truck. Heck, now a 70 mph speed limit essentially means 75-80 here in Texas, which the truck simply doesn't like.
Funny, because I remember driving freeways in cars with 27" tires and 3.7x gears back in the day, and we never even thought about needing another gear. Had a friend with 4.11 gears in a 60s Corvette who used to drive a 500 mile round trip twice a month to see his girlfriend. He said the same thing -- he doesn't remember the high revs being an issue.
Heck, I'll probably just end up with an OD trans, but then my 3.08 gears will be a little tall. Damned if I do...
