Thanks for all the replies. I've only driven it about 90 miles from the dealer home last night and once I got out of the city there was little other traffic on the interstate so I was able to experiment a bit. The MPG goes down drastically above 70 so I kept the cruise at about 65 most of the trip. The tranny did do a bit of shifting on uphills when in Drive. In Tow/Haul mode the RPMs were too high for my liking. Guess I'll be slowing down a bit from my old TC speeds.
