Beautiful trip. Highway 101 is a major highway with only a few tight spots. An easy lovely drive with plenty of places to stop. Highway 1 is the road closest to the ocean. In many places it is the 101. Only the drive between Carmel and Morro Bay in California is to be missed. This is often listed as one of the most beautiful drives in the West, but in an RV you will be on the wrong side of the road, with shear drops into the rocks and ocean, hair pin turns so tight you see your own tail, and only two narrow lanes, with traffic driving much too fast in either direction. This is a good place to rent a car and make it an all day drive through Big Sur. The rest of the drive, through Washington, Oregon, Northern Ca, is safe and wonderful. Best to you and Happy Trails.
