Since you have a fuel injected motor you should be fine with the altitude. Its going to be a little sluggish than what you are used to though because of the altitude, should get better after the computer adjusts to less oxygen. I would just suggest getting some sand bags in the bed for more weight over the rear tires before you hit the rockies. You never know what kind of snow you will hit over the pass. I keep them in the bed of my truck all winter long over here, helps with the traction on snowy roads of course... Good luck! let me know how you move goes!
