I do the "gorge" every year (sometimes twice) it is a twisty turny road with some up and down. I have a 2500 DMAX and a 39"+ travel Trailer. I follow a truck if he is dong the speed limit. If not I'll pass him and follow the next truck.. These guys do this run daily. It lasts for about 45 minutes then go back to the foot hill thing. Stay back from the guy in front of you as sometimes they need to brake and you will too. It is kinda fun after driving across TX, NM and other not so interesting states. The other thing I forgot was I do this at about 4:30AM in the pitch dark and in early spring when there are still snow storms and such but still with out a hitch (rv humor there). Have fun
