We have a similar setup as yours. Not sure what kind of info you're looking for exactly... We took I70 east from Moab a couple of months ago. The trek to the Eisenhower tunnel was slow, as you can expect. If your truck is running well, you will be OK. Just don't try to climb the hill at 65, let the truck dictate the speed; I think most of that hill we did around 37 mph and let the tow/haul do its work and settled in nicely at that speed and gear; the tranny got hotter and the engine got hotter, but all still within safe/acceptable ranges for the load and hill. Just take it steady and easy.
Coming down the other side of the hill was very manageable in terms of speed (do not speed up during the flat part at the tunnel, keep your speed the same as what you climbed at), the Allison tranny did great at keeping the speeds low in tow/haul mode, but the road itself down the hill is terrible, it's badly grooved by the semi's.
We really enjoyed Moab and want to go back... once over the Rockies, we went in the opposite direction to Colorado Springs, but I like the northern part of the state even more.
Enjoy your trip!
