I am looking for a rv friendly route from Port Angles, Wa. to Tucson, Az. I do not want to take I-5 because it has to many mountain passes in Oregon and N. California. I also do not want to have to drive thru the LA area. I am thinking of going thru Boise, Id and then down US 93 into Nevada. I need to be in Tucson in three days. Any suggestions?
