We are planning a late summer trip to Yosemite, Kings Canyon, and Sequoia National Parks. We are taking I-80 west to I-580 down to Carson City, NV, and then to Stockton, Modesto, and Merced in CA. Our trip planner shows a CA route 88 to Stockton. It looks like there are some switchbacks along the way while going over the mountains. Is that route okay for our Beaver?
