I travel between Carson City and Tucson through Las Vegas every year and use Hwy 95. Watch the weather in Tonopah, NV. It's about 6,100 feet and can get snow in April. It also can get very windy without warning so keep both hands on the steering wheel.
I don't have any info on boondocking as we use one of the $25.00 per night parks.
