It's not too bad. It's just like any other mountain pass. Don't let your rig overheat. Gear down and pull at a speed your truck likes. Stay in the slow lane unless it's absolutely necessary to pass a really slow vehicle. If you do need to pass, make sure you have plenty of room if you are going at a slower speed. Some of the cars pull the pass at 75-80 mph, so you won't give them a lot of time to react if you change lanes at a slow speed. Hundreds of RVs and big rigs make the climb daily, and you shouldn't have a problem at all.
