Long Roadtrip in Yukon 2500?

[Woldy1]

Thanks for all the great advice! My trip was moved to a different month so I have some more time to prepare, The Trans fluid was changed recently at 187k miles about 14k miles ago but fluid looks a brown, Should I change it?

Brown? Yes change it. I would drive cross country in mine. Love it! And I usually drive it almost everyday. Enjoy your trip!
