This looks like Hwy 97 just north of Weed, CA to me. Beautiful area.
My favorite road trip car was my 1990 Daytona base model. 2.5L 5-speed. The seats were so comfortable. Wasn't fast and didn't get amazing fuel economy, but very comfy.
Second to that was my dad's 1992 Dodge 2wd 3/4 Cummins with captains chairs. Nice truck that just hummed down the highway.
