Hwy 50 (the Loneliest Road) though Nevada is one of my favorite routes. This is a two lane highway with a lot to see and do. Grimms point petroglyphs, Sand Mountain, Pony Express stations, old mining towns like Austin & Eureka, Hickison Petroglyphs and you pass right near Great Basin National Park.

Hwy 50 in California is a scenic drive too. If you decide to take I-80 to Reno, then you can pick up Alt 50 in Fernley, NV I just checked gas prices using GasBuddy and currently Fernley, Fallon & Ely, NV & Delta, UT have gas cheaper than Reno, NV. Austin, NV was a good 40+ cents higher so I would avoid having to get gas there.
